液相法制备钛酸锶铅粉的研究

Study on the Preparation of Strontium Lead Titanate by Liquid Phase Homogeneous Precipitation

研究了反应温度、酸碱度、放置时间和煅烧温度对化学共沉淀法制得的钛酸锶铅粉末的影响,探讨了其热分解过程,用XRD、SEM、DTA和EPMA对粉体进行了综合分析,得到了纯度较高的钛酸锶铅粉末.

Strontium lead titanate powder has been prepared from strontium lead titanyl oxalate tetrohydrate by chemical copre-cipitation.The effects of reactive temperature, pH value, reactive time and heat treatment temperature were investigated. Its thermal decompositive mechanism is analysized.
