Gelcasting, slipcasting and roll forming were used to prepare chip PTCR in this paper, the effects of forming process on the characteristics of green tapes and ceramic samples were investigated.

• 将注凝成型、注浆成型与轧膜成型应用于片式PTCR的制备,研究了不同成型工艺对片式PTCR素坯及瓷片性能的影响。研究发现,用注凝成型和注浆成型工艺制备的素坯比用轧膜成型更加均匀,其陶瓷颗粒与粘结剂分布规则。
