Rhodium powder is an important metal powder prepared from high-purity rhodium metal. Rhodium is a rare and precious metal belonging to the platinum group element, with excellent chemical properties and unique physical properties. Rhodium powder is widely used in various fields, including catalysts, electronic devices, glass processing, cosmetics, and jewelry.

There are various methods for preparing rhodium powder, among which the following are several common preparation methods:

1. Hydrothermal method: Hydrothermal method is a commonly used method for preparing rhodium powder. First, the rhodium salt (such as rhodium chloride) is mixed with an appropriate amount of reducing agent (such as Polyvinylpyrrolidone), and added to an appropriate amount of aqueous solution to form a mixture. Then, place the mixture in a high-pressure container and react under high temperature and pressure conditions. After a period of reaction, the resulting precipitate is collected, washed, dried, and other treatments are carried out to obtain pure rhodium powder.

2. Chemical reduction method: Chemical reduction method is another method for preparing rhodium powder. This method mainly uses chemical reducing agents to reduce rhodium salts to pure rhodium metal. The reducing agents commonly used are hydrogen, sodium hydroxide, etc. Firstly, mix the rhodium salt with a reducing agent and react under appropriate conditions to reduce the rhodium salt to metallic rhodium. Then, rhodium powder is finally prepared through steps such as precipitation separation, washing, and drying.

3. Gas phase method: Gas phase method is a method of preparing rhodium powder under high temperature and pressure conditions. The commonly used gas-phase methods include gas-phase reduction and thermal decomposition. In the gas phase reduction method, the rhodium compound in the gas phase is exposed to a reducing atmosphere to undergo a reduction reaction, ultimately obtaining rhodium metal powder. The thermal decomposition law involves decomposing rhodium containing compounds under high temperature conditions to convert them into metallic rhodium.
