What are the primary uses of Platinum?

Answer 1

Applications

* As a catalyst in the catalytic converter, an optional (though often mandatory by law) component of the gasoline-fueled automobile exhaust system (see "Notable characteristics" in this article).
* As a catalyst in fuel cells. Reducing the amount of platinum required (and thus cost) is a major focus of fuel cell research.
* Certain platinum-containing compounds are capable of crosslinking DNA and kill cells by similar pathways to alkylating chemotherapeutic agents. Cisplatin, carboplatin and oxaliplatin are licensed examples of this class of drugs.
* Platinum resistance thermometers.
* Electrodes for use in electrolysis.
* In the Clark polarographic electrode for measuring oxygen tension.
* A wide range of jewelery
* As a catalyst in the curing of silicone elastomers.
* As a catalyst in glow plugs in some model engines.
* Crucibles for high temperature melting of glass (for example) up to 1500°C,

better if alloyed with rhodium (10-40% of Rh).

* In photography, it is used for archival printmaking.

Answer 2

Platinum is used in jewelry, laboratory equipment, electrical contacts, dentistry, and automobile emissions control devices.
