Rhodium powder is gray-black powder, with highly resistant to corrosion and even insoluble in boiling royal water. But hydrobromic acid slightly corrodes rhodium, as do moist iodine and sodium hypochlorite. Rhodium's fine chemical products include rhodium trichloride, rhodium phosphate and rhodium sulfate, rhodium triphenylphosphine and rhodium trioxide, etc. Mainly used in the preparation of chemical catalysts, the surface plating of electronic components rhodium or rhodium alloy, the modulation of electronic slurry and the preparation of gold water and bright palladium water.

Applications:
1. It can be used as raw materials for electrical instruments, chemical industry and precision alloy manufacturing;

2. As one of the rare elements, rhodium has various uses. Rhodium can be used to make hydrogenation catalyst, thermocouple, platinum and rhodium alloy, etc.

3. It is often plated on the searchlight and reflector;

4. Also used as a polishing agent and electrical contact part for precious stones.
