Description

Rhodium(III) Nitrate Dihydrate is a high-purity inorganic salt of the precious metal rhodium, commonly used as a precursor in advanced material synthesis. Its primary value lies in providing a soluble and reactive source of rhodium ions for catalytic and coating applications. This compound is essential for R&D and production in sectors such as electroplating, heterogeneous catalysis, and the manufacture of specialty chemicals and electronic components.

Application

• Catalyst Precursor: A key starting material for synthesizing homogeneous and heterogeneous rhodium-based catalysts used in hydrogenation, hydroformylation, and carbonylation reactions.
• Electroplating & Surface Finishing: Used in electrolyte formulations for the electrodeposition of rhodium coatings, which provide exceptional hardness, corrosion resistance, and electrical conductivity on connectors and jewelry.
• Chemical Vapor Deposition (CVD): Serves as a volatile source compound in CVD processes to deposit thin films of rhodium or rhodium oxide for semiconductor and optical applications.
• Research & Development: Employed in academic and industrial labs for developing new catalytic systems, sensor materials, and coordination chemistry studies.
• Specialty Chemical Synthesis: Acts as an intermediate in the preparation of other organorhodium compounds and complexes with specific catalytic activities.
• Glass & Ceramic Industry: Used in the formulation of conductive pastes and specialty pigments where rhodium's unique properties are required.

Quality Control

Our Rhodium(III) Nitrate Dihydrate is produced and handled under strict quality management protocols to ensure batch-to-batch consistency and high chemical purity. Each lot is analyzed to confirm identity, assay, and impurity profiles. Certificates of Analysis (COA) detailing specific results for Rhodium content, nitrate content, and trace metal impurities are provided and available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept sealed to prevent moisture absorption and decomposition. Keep away from incompatible materials such as strong reducing agents and organic substances.
