Platinum is regarded as a precious metal like gold and silver. Some of the characteristics of this metal which has made it increasingly popular with its applications in various fields are ductility, malleability, resistance to corrosion and oxidation, catalyzing ability, high coefficient of expansion and good conductance of electricity.

Some of the areas where platinum has found utility are:

• Jewels: Due to the hardness and toughness of this metal, it is being used widely in making jewels especially those in which precious stones are embedded. It adds to the brilliance and reflectivity of the jewel.
• Catalyst in chemical processes: This is an excellent catalyst in processing fertilizers, synthetic fibers, petroleum and nitric acid. Since the catalyst only assists the process and does not consumed like an ingredient, they can be recycled and used repeatedly.
• Electronic industry: Since platinum conducts electricity very well, it is used in electric circuits, optical storage devises, thermocouple systems, wires and devices for sensing temperature.
• Automotive industries: It is used primarily as a catalyst is converting hydro-carbons which are not burnt in to water and carbon-dioxide. It is used as sensors for oxygen, electrode in the spark plugs and as fuel cells in electrically driven cars.
• Glass industries: Factors like density, high temperature for melting and hardness make it a good option for use in manufacturing fiber glasses.

Apart from the above mentioned uses, platinum is also gaining popularity in medicines, computers and lasers also. Lately, people have started opting to invest in platinum as an asset in coin form or bar form.
