One of the major applications of platinum is its usage as a catalyst in chemical reactions. In automobiles, it is used as a catalytic converter that permits the entire combustion of low cons of unburned hydrocarbon from the exhaust into CO2 and water vapour. It is also used as a catalyst in the petroleum industry in many processes. PtO2 or Adams’ catalyst is used as a hydrogenation catalyst for vegetable oils. Platinum is used as a Standard for various measurements. The length of a platinum-iridium (90:10) alloy bar is used to define meter from 1889 to 1960 and it is also known as the International Prototype Meter bar. A cylinder of the platinum-iridium alloy made in 1879 is used to define the International Prototype Kilogram.

Platinum is a precious metal commodity and its coins, bars, and ingots are used in trading. Platinum is an inert element and shines well therefore; it is used in jewellery as a 90-95% alloy. It is also used in watch-making with Patek Philippe, Rolex, and other companies are using it for producing watches for their limited edition watch series. The platinum wire is used for electrodes in the laboratory. The platinum pans are used for thermo-gravimetric analysis and it is used as an alloying agent for different metal products like fine wires, medical instruments, dental prostheses, noncorrosive laboratory containers, electrical contacts, as well as thermocouples. The permanent string magnets are made from the alloy of platinum-cobalt. Platinum-based anodes are widely applied in steel piers, ships, and pipelines.

As platinum is considerable denser as compared to many of its impurities, the lighter impurities are removed by merely the process of floating them in a water bath where the impurities will get flown away. Platinum is non-magnetic in nature while the nickel and iron are magnetic. To remove these two impurities, an electromagnet is run over the mixture. Many impurities can be burned or melted away without affecting platinum as it has a higher melting point than many other substances. Moreover, platinum is resistant to acids like hydrochloric and sulfuric acids, metal impurities can be easily separated by stirring the mixture in any of these two acids and then obtaining the remaining platinum.

Another widely used method is the processing with aqua regia for the purification for the raw platinum containing platinum, gold, as well as the other platinum group metals. In this procedure, the elements like palladium, gold and platinum are dissolved and on other hand ruthenium, osmium, rhodium and iridium stayed un-reacted. The precipitation of the gold is done by the addition of iron(III) chloride. Once the gold is filtered, the precipitation of platinum is done by the addition of ammonium chloride in form of ammonium chloroplatinate. The platinum is obtained by heating the Ammonium chloroplatinate.

In case you have limited budget for investing in platinum then you should purchase the coin type or ETF. This platinum price varies daily as per the supply and demand of the platinum. The platinum investment has 2 types including the physical platinum investment and the non-physical platinum investment. The physical platinum investment focuses on owning a precious metal like purchasing bar or platinum coins. In case you would like to invest entirely on platinum then you should purchase the platinum investor coin instead of the collectible. The collectible coins are more costly as compared to other one. The wafers as well as bars are sold with little premium, but they are not available like the coins.

The non-physical platinum investment involves investing in shares of platinum mining firms or by purchasing into platinum based ETFs. If you like to invest in collectible coins, you should be ready to spend more as they are more expensive as compared to their face value. It is advised that you should check the condition of the coin to see if there is any dent and scratches are there. You should also need to check the age of the coins and when it was minted because the older coins are more expensive.

The Cathedral or Contour setting is that setting where a stone is kept high by using the raised shoulders that assist in protecting the diamond. The Tension setting allows the users to pressurize the stone firmly in place to reflect maximum light. The smaller stones make a statement on a wedding band for adding extra sparkle to a platinum ring, bracelet or pendant. The Bar setting refers to a thin metal bar that separates each stone and left the sides open for light to come in. A Flush setting is a low stress setting that keeps the small stones secure inside small holes. The Channel setting refers to the setting where the stones are placed in a metal channel and they are visible. They build a regular flow with no metal for separate them. A Pave setting reflects the setting that creates a sparkling look of diamonds where tiny metal beads usually hold each stone in its distinct setting.

The antioxidant properties of the platinum nanoparticles are the subject of substantial research in applications encompassing nanotechnology, medicine as well as in the synthesis of novel materials with exceptional properties. These nano-particles are made-up by reduction of the hexa-chloroplatinate. Once the hexachloroplatinate is dissolved, the solution is stirred continuously and a reducing agent is added. It results in platinum ions to get reduced to neutral platinum atoms. With the formation of large number of platinum atoms, the solution becomes supersaturated and eventually started to precipitate in the form of sub-nanometre particles. The remaining platinum atoms got attached to the existing particles and in case the solution is stirred vigorously, the particles become uniform in size.

The platinum nanoparticles offer various safety issues medically as well as environmentally. The basic reason behind these issues is the high surface to volume ratio that renders the particles very reactive or catalytic. It is dangerous to inhale the platinum nanoparticles and may lead to inflammation and disease in the lungs. They can readily pass across the cell membranes in the humans and other organisms. Moreover, their interactions with biological systems are not known. The free nanoparticles get agglomerated in the environment quickly and thereby leaving the nano regime.

One drawback is that you need to have an excellent credit ranking and a certain amount of annual income for getting it. By keeping the high standards, the companies make it hard for some men and women to receive a platinum credit card. It may look unfair but credit companies make their own decision as who would be able to receive a platinum credit card. Among the benefits of having a platinum credit card is that you are eligible to receive a lower interest rate as compared to other credit cards. You can also take the benefits of many kinds of rewards. You can receive the rewards in form of a travel, cash, or gas from different credit card companies.

In some cases you may get the cash back or points reward. You can also transfer your credit cards with higher interests to your platinum credit card and then get a lower interest rate in doing so.

It might require you to fulfil the credit and income standards. In reality the benefits offered by platinum credit card overcomes some of the drawbacks that comes with it. Ideally, the usage of platinum card will offer the best of the advantages to you.

As per the market research, the demand for platinum is increasing and it will reach to 15 tonnes by the end of 2010-11 as compared to 10 tonnes in 2008-09. The price of platinum was double the price of gold. However, it has reduced to match cost of the yellow metal. Therefore, many investors who regarded it as too expensive metal can now purchase it. The metal offers the re-sale value in line with gold jewellery items and therefore it is a better investment for the consumers.

The platinum in jewellery form was famous in few selected countries in the beginning such as Japan, the US and China. In India, the metal was considered chiefly for industrial consumption, photography and as an auto catalyst. Efforts were made about increasing the awareness of metal’s potential in jewellery and this has led to generation of huge demand in urban India. The platinum’s consumption would soon pick up in India if the spot quotes as well as premiums are made available at each retail shop.

Moreover, China started minting platinum coins in 1987 by issuing 2000 quality proof pieces along with face value of 100 Yuan. It is about 99.95% in composition that contains 1 ounce of platinum.

China also minted platinum panda coins, in different denominations and amounts in the year 1988-1990, 1993-1997, and 2002-2005. The Russian Empire also prepared the legitimate platinum coins in the 1800s while the Soviet Union also prepared platinum coinage. The imperial platinum coinage is not famous. The Soviet Union and later the Russian Federation produced large number of platinum coins in denominations of 25, 50 and 150 rubbles. At present, this trend is discontinued. The British Royal Mint also minted the Platinum Britannia bullion coins.

The Platinum colour is basically a colour that pale greyish-white with metallic tint and resembles the metal platinum. The use of platinum colour takes place in the year 1918. Platinum plays a unique role in human culture. Apart from coins, colour, jewellery and industrial usages, the word platinum assumes significance in other areas as well. A platinum award is regarded as a prestigious award that is above gold, silver, or bronze award. A platinum credit card offers higher credit limit and a less interest rate as compared to regular credit card.

The naturally occurring platinum and its alloys were known to pre-Columbian Americans for a long time, however the first European reference appears in 1557 in the work of the Italian writer Julius Caesar Scaliger. He wrote about the mysterious metal found in Central American mines. The Spaniards coined the name ‘’platina” when they first saw it in Colombia. They considered platinum as an unwanted impurity in the silver which they were mining. The platinum metals exhibits exceptional catalytic properties and they are extremely resistant to wear and tarnish. In fact, platinum is widely used for fine Jewellery.

Among other unique properties are the resistance to chemical attack, stable electrical properties and excellent high-temperature characteristics. All these properties are being used in wide range of industrial applications. The production of pure platinum group metals begins from the residues of the production of other metals with a mixture of many such metals. One of the starting products is the anode residue of gold or nickel production. They are separated by using the differences in chemical reactivity and solubility of various compounds of the metals. The various elements in this group get separated by dissolving all the metals in aqua regia and forming their respective nitrates. After that, various procedures are used for extracting each of them separately.
