Product name: rhodium
Model Specifications: silver-white metal with extreme hardness, wear-resistant and considerable ductility
At moderate temperatures, rhodium can resist to most common acids (including aqua regia) but can react with hot concentrated sulfuric acid, hot hydrobromide, sodium hypochlorite and halogen-free within the 200~600℃ temperature range. Rhodium does not react with most of the molten metal, such as gold, silver, sodium and potassium, and molten alkali.
Rhodium is widely used in the manufacturing of alloys, such as platinum-rhodium alloys, and also used to manufacture hydrogenation catalysts, thermocouples and hard-bright coating for other metals, for example coating in silverware, camera parts, searchlights and mirrors. In addition, rhodium is also used as polishing agent for gemstones and electric contact parts. It is a rare and precious metals, with a wide usage range in many industries.
