Product Overview & Quality Standards

Rhodium nitrate (Rhodium nitrate solution) 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.

Rhodium (Rh) content: ≥35.0%
Iron (Fe) content: ≤0.001%
Total metal impurities: ≤0.005%

Primary Applications

1. Precious Metal Catalysts

Functions as a crucial precursor for high-performance precious metal catalysts utilized in industrial synthesis and chemical reactions.

2. Oxidant

Widely utilized as an effective oxidizing agent across various chemical processing and industrial manufacturing stages.

3. Thermocouples

Key material used in the specialized preparation and manufacturing processes of precision temperature thermocouples.
