  • Stabilized hydrous pentavalent antimony oxide sol composition and its production, production of dry powder from sol composition and resulting dry powder
    Patent number: 4028266
    Abstract: 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.
    Type: Grant

    Date of Patent: June 7, 1977
    Assignee: NL Industries, Inc.
    Inventors: Ronald Francis Langere, Otto Ernest Loeffler
  • Production of hydrous pentavalent antimony oxide sol composition, dry powder prepared therefrom, and production of said dry powder
    Patent number: 4026819
    Abstract: An aqueous antimony pentoxide sol composition, comprising from 10% to 50% antimony pentoxide and the remainder water has been prepared. This sol composition also may contain up to 5.0% of an amine if desired. When this sol composition contains the amine, a dried composition may be obtained from this sol composition. This dried powder contains from 85% to 95% antimony pentoxide and from 2.5% to 10% of an amine, the remainder being absorbed and combined water. This dried composition when added to water or an organic solvent readily forms the stabilized sol composition originally obtained.
