【摘要】 用液相复分解法 ,在不同的Na2 WO4 溶液浓度、起始pH值、温度、摩尔比及加钇溶液的速度等条件下制备钨酸钇。用激光粒度分析仪测定其各反应条件下产品粒度。优选出制备具有较好粒径分布、粒径小产品的制备条件。更多还原

【Abstract】 Yttrium tungstate was systhesized by liguiel-phasic polydecomposition method under the following conditions:different concentration of Na 2WO 4,starting pH value,temperature,molar ratio and the speed of adding Y solution.The particle size of product prepared under different reaction conditions was measured by laser particle size analyzer.The reaction conditions were optimized for preparing products with small particle size end good particle diameter distribution.更多还原
