Stabilized hydrous pentavalent antimony oxide sol composition and its production, production of dry powder from sol composition and resulting dry powder

摘要

An aqueous stabilized antimony pentoxide sol composition, comprising from 25% to 35% antimony pentoxide, from 6.5% to 17% of an amine and the remainder water, has been prepared. A dried composition obtained from this sol composition has also been prepared. The dried powder contains from 62% to 76% antimony pentoxide, from 17% to 32% of an amine and the remainder absorbed and combined water. This dried composition when added to water or an organic solvent readily forms the stabilized sol composition originally obtained.
