Minute powdered three oxidation antimony - production manner null of antimony pentoxide amorphous compound

摘要

PURPOSE:To obtain the titled high-purity composite oxide available as a nonflammable aid, a catalyst and a pigment by hydrolyzing a reaction product of Sb(III) alkoxide and Sb(V) alkoxide. CONSTITUTION:The decarbonated distilled water is added to a reaction product obtained by mixing Sb(III) alkoxide of a formula Sb(OR)3 (R is alkyl group of alcohol) and Sb(V) alkoxide of a formula Sb(OR)5 in an organic solvent (e.g. benzene) and allowing both to react at 0-120 deg.C and the mixture is hydrolyzed to obtain the fine powdery Sb2O3-Sb2O5 composite powder.
