【摘要】 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 。更多还原

【Abstract】 The transitions of lead oxide and BaCO 3 during the heating are researched in this paper;BaPbO 3 ceramic powder has been prepared by means of solid phase method with BaCO 3 and Ph 3O 4 as the raw powders. The influences of calcination temperature and the heating rate on the powder’s phase composition are investigated by X ray diffraction and scanning electron microscope Proper synthesis of BaPbO 3 temperature is determined for solid phase preparation更多还原
