Platinum powder is excellent against corrosion and oxidative processes in contact with aggressive substances, vapors and gaseous substances.
It has a silver gray color. It differs in the form and weight of granules, bulk density, brand of raw materials.
Produced by pressing, grinding. Melts at high temperatures.
It has a greater degree of chemical resistance compared to palladium powder. It has maximum chemical inertness. Insoluble in acids and alkalis.
It has the properties of a catalyst.

The particle size of the powder generally does not exceed 1.6 mm. Particles larger than 1.6 mm are allowed in an amount of not more than 2% by weight of the lot.
Platinum powder is used in powder metallurgy as an alloying component, in laboratory studies as a catalytic agent. Serves as raw materials for the manufacture of medical instruments, jewelry, dental and surgical prostheses and implants, chemical glassware and equipment, permanent magnets, electroplating and decorative coatings, anodes, heating coils, etc.
