METHOD FOR PRODUCING ANTIMONY OXIDE SOL AND ANTIMONY OXIDE SOL

摘要

PROBLEM TO BE SOLVED: To produce an antimony oxide sol excellent in transparency and stability and having a large particle diameter and a uniform particle size distribution.;SOLUTION: In a method for producing an antimony oxide sol by reacting antimony trioxide with an alkali material, then reacting it with hydrogen peroxide, next subjecting it to a deionization treatment, and then aging it, the antimony trioxide comprises antimony trioxide having an orthorhombic crystal form and a cubic crystal form, the content of the antimony trioxide having a rhombic crystal form is in a range of 15-40%, the mole ratio of the antimony trioxide, the alkali material and the hydrogen peroxide is in a range of 1:2.0-2.5:0.8-3.5, and the aging temperature is in a range of 50-200°C.;COPYRIGHT: (C)2007,JPO&INPIT
