摘要
高纯ＣａＣＯ３的合成方式对ＣａＣＯ３粒子形貌有较大影响，对ＰＴＣ陶瓷的电性能也存在一定的作用，其中以气液反应合成方式所得ＣａＣＯ３对ＰＴＣＲ较适宜。
The synthesis method of high purity CaCO 3 has significant influence on shape of CaCO 3 grains and effect on electrical properties of PTC ceramics. The CaCO 3 synthesised by gas liquid reaction has appropriate effect on those of PTCR.
