对加热 过程中 铅的氧化 物及碳 酸钡发生 的变化进 行了研 究;采用固 相法,以 Ba C O3 和 Pb3 O4为原料制 备了 Ba Pb O3 陶 瓷粉末; 对焙烧粉 末进行了 X 射线衍射 检测及 扫描电镜 观察,分 析了不同 焙烧温度、不 同升温 速度下粉 末的相 组成,从而 确定了 固相法制 取 Ba Pb O3 的 合成温度 。
The changes of lead oxide and barium carbonate in the heating process were studied. Ba Pb O3 ceramic powders were prepared by solid-state method using Ba C O3 and Pb3 O4 as raw materials. X-ray diffraction Scanning electron microscopy was used to analyze the phase composition of the powders at different calcination temperature and different heating rates to determine the synthesis temperature of Ba Pb O3 prepared by solid state reaction.
