STUDY ON THE PREPARATION OF STRONTIUM LEAD TITANATE BY LIQUID PHASE HOMOGENEOUS PRECIPITATION

摘要: 采用化学共沉淀法经前驱体草酸氧钛锶铅制得钛酸锶铅粉末。在分析前驱体的形成机理及热分解机理的基础上, 采用XRD、SEM、DTA、EPMA 等现代分析手段对粉体进行综合分析,并详细探讨了反应温度、酸碱度、热分解温度对产物的影响。

Abstract: In this paper, strontium lead titanate was prepared from strontium lead titanyl oxalate tetrohydrate by chemical coprecipitation. XRD, SEM, DTA, EPMA were used to analyze the powder. The effects of reactive temperature, pH value and heat treatment temperature were investigated after studying its formation and thermal decompositive mechanism.
