Product Name:Cadmium hydroxide
English Name:Cadmium hydroxide
CAS No.:21041-95-2
Aliases:Cadmium dihydroxide, Cd(OH)2
Molecular Formula:Cd(OH)2
Physical Properties:White amorphous powder or trigonal/hexagonal crystals. Density 4.79 g/cm³ (15°C). Absorbs carbon dioxide in air. Begins to decompose at 150°C and completely decomposes at 300°C. The hydrated form loses water starting at 130°C and completely at 200°C. Almost insoluble in water, slightly soluble in sodium hydroxide solution, soluble in dilute acids, ammonium hydroxide and ammonium chloride solution, and forms complex ions in ammonia solution. Toxic and potentially carcinogenic.
Uses:Used for producing nickel-cadmium batteries, preparing other cadmium salts, and applied in metal surface treatment, gas chromatography analysis, and electronic component materials.
Technical Specifications:
Purity: ≥99%
Appearance: white amorphous powder or trigonal/hexagonal crystals
Density: 4.79 g/cm³ (15°C)
Thermal stability: decomposes from 150°C and completely at 300°C
Solubility: almost insoluble in water, soluble in dilute acids and ammonia
