Description
Rhodium nitrate (Rhodiumnitratesolution) is prepared by the action of rhodium and nitric acid, and reacts with alkali to generate lemon yellow precipitated rhodium trioxide pentahydrate. It is a red or yellow deliquescent crystal. Because it is a precursor of an important catalyst in industrial production, it is widely used in industry. In addition, it is often used as an oxidant.
Quality Specification
Rhodium (Rh) content: ≥35.0%; Iron (Fe) content: ≤0.001%; Total metal impurities: ≤0.005%.
Application
1. Precious metal catalysts
2. Oxidant
3. For the preparation of thermocouples
