Rhodium powder is hard and brittle, has strong reflection ability, and is particularly soft under heating. Rhodium has good chemical stability. Rhodium has good oxidation resistance and can maintain gloss in the air for a long time.

The automotive industry is the largest user of rhodium powder. At present, the main use of rhodium in automobile manufacturing is automobile exhaust catalyst. Other industrial sectors that consume rhodium are glass manufacturing, dental alloy manufacturing, and jewelry products.

With the continuous development of fuel cell technology and the gradual maturity of fuel cell vehicle technology, the amount of rhodium used in the automotive industry will continue to increase.
