摘要
陶瓷添加剂能使陶瓷材料具有良好的烧结状态和最佳的压电性能。本文作者采用Ｄｕｐｏｎｔ—２０００型热分析仪对常用添加剂ＭｎＯ２、Ｆｅ２Ｏ３、Ｌｉ２ＣＯ３进行了ＤＴＡ、ＴＧＡ分析，研究了几种物质在烧结过程中的物理、化学变化。
The dopants can make the ceramic materials a excellent piezoelectric with good sintering ability.In this paper,the differential thermal analysis and thermogravimetric analysis were made on the usual dopants MnO 2,Fe 2O 3 and Li 2CO 3 using Dupont 2000 thermal analyzer.The physical and chemical changes of these dopants were investigated in the sintering procedure.
