Product Name:Indium Hydroxide
English Name:Indium Hydroxide
CAS No.:20661-21-6
Aliases:Indium(III) hydroxide, Indium trihydroxide, Trihydroxyindium
Molecular Formula:In(OH)₃
Physical Properties:White amorphous powder or colloidal precipitate, odorless. Relative density approx. 4.4. Insoluble in water and ammonia solution; readily soluble in inorganic acids such as hydrochloric, nitric and sulfuric acids; soluble in strong alkali solutions to form indates. Amphoteric hydroxide; begins to dehydrate above 150 °C and finally decomposes to indium oxide (In₂O₃).
Uses:Used as a raw material for preparing high-purity indium compounds such as indium oxide and indium trichloride. Widely applied in the manufacture of ITO (indium tin oxide) sputtering targets, semiconductor materials, gas sensors and catalysts. Plays an important role in liquid crystal displays, solar cells and optoelectronic device fabrication.
