环氧丙烷辅助制备ZrO2-SnO2复合溶胶的通用方法
A General Propylene Epoxide-assisted Sol-Gel Route for the Synthesis of ZrO2-SnO2 Composite Sols
摘要
Abstract
Using zirconium chloride and tin chloride as precursor,ZrO2-SnO2 composite sol was prepared with auxiliary of the propylene epoxide.The influences of the various additives and solvent composition on pH and gel time variation were investigated.In addition,structure and composition of the Xerogel after heat treatment were investigated with TG-DTA and XRD analysis.2wt％ ZrO2-SnO2 composite sol could be synthetized when RPO/Cl =1.5/1,VW/E =1/3 and dilute nitric acid amount was 1.5ml/100ml.Mean particles size of sol was about 33.5 nm.The Xerogel heat-treated at 500℃ ～ 550℃ was consist of orthorhombic ZrSnO4,tetragonal phase ZrO2 and SnO2.关键词
