Product performance

Gray-black powder, high corrosion resistance, even insoluble in boiling aqua regia.

Storage conditions

This product should be stored in dry, cool and sealing of the environment, can not be exposure to air, in addition should avoid the heavy pressure, according to ordinary goods transportation.


It can be used as a raw material for electrical instruments, chemicals and manufacturing precision alloys. Rhodium powder is based on the extensive use of ruthenium in the industrial chemical industry. Because rhodium is a rare metal required by industry, the industry price is slightly higher than that of general non-ferrous metals. As one of the rare elements, rhodium has many uses. Rhodium can be used to make hydrogenation catalysts, thermocouples, platinum-rhodium alloys, etc. It is also often plated on searchlights and reflectors, and it is also used as a polishing agent for gems. And electrical contact parts.
