rhodium

Specification and model: Rhodium is a silver white metal that is extremely hard, wear-resistant, and has considerable ductility.

Rhodium is commonly used in the manufacture of alloys, such as platinum rhodium alloys; It is also used to manufacture hydrogenation catalysts, thermocouples, and other bright and hard coatings, such as on silverware or camera parts, on searchlights and reflectors. It is also used as a polishing and electrical contact component for gemstones. It is a rare and precious metal with a wide range of industrial applications.

At moderate temperatures, it can resist most common acids (including aqua regia). inIt can react chemically with hot concentrated sulfuric acid, hot hydrobromic acid, sodium hypochlorite, and free halogens at temperatures between 200-600 ℃. Not reacting with many molten metals such as gold, silver, sodium, and potassium, as well as molten bases.

Usage: Suitable for gold ingots produced from various gold raw materials.
