English description（英文原文，共 1182 字符）
Product Name:Holmium(III) acetate
English Name:Holmium(III) acetate
CAS No.:25519-09-9
Aliases:Holmium acetate hydrate, Holmium triacetate, Acetic acid, holmium salt
Molecular Formula:Ho(C2H3O2)3·xH2O
Physical Properties:White to pale yellow crystalline powder, readily soluble in water, soluble in dilute acids, slightly soluble in ethanol; gradually loses water of crystallization upon heating and decomposes to holmium oxide at high temperature. The aqueous solution is weakly acidic and hygroscopic; keep sealed and dry.
Uses:Used as a precursor for rare-earth doped materials in the preparation of laser crystals, optical glasses, and phosphors; serves as a rare-earth catalyst in organic synthesis; also utilized as a reference standard in spectral analysis and for producing high-purity holmium oxide.
Technical Specifications:
Rare earth content (as Ho2O3): 99.0% – 99.99%
Appearance: white to pale yellow crystalline powder
Solubility: readily soluble in water, soluble in dilute hydrochloric acid and dilute nitric acid
Loss on ignition (800°C): conforms to theoretical value of the hydrate
Impurity content (Fe, Ca, Cu, etc.): ≤10 ppm each (high-purity grade)
