摘要
根据我国最近制定的《电子陶瓷用钛酸钡粉体材料规范》规定的钛酸钡粉体材料预定用途和理化性能指标，评述了各类质量等级的钛酸钡粉体材料在ＰＴＣ陶瓷方面的应用范围，解释了某些理化性能指标在ＰＴＣ陶瓷配方设计和工艺中的实用意义。
Based on the predefined applications and the indexes of physical-chemical characteristics of barium titanate powder materials specified by the newly enacted SPecificotion of barium titonate of powder material used in electronic cermics,the application ranges of various classes of barium titanate powder mater-ials in the aspect of PTC ceramic are discussed in this paper,and the practical meaning of certain indexes of physical -chemical propertied for the compositional design and process of PTC ceramics is also explained.
