摘要
采用草酸盐和铵盐溶液法制备PTCR热敏陶瓷的前驱体(Ba_xSr_(1-x))TiO_3和(Ba_yPb_(1-y))TiO_3,加入半导化剂Sb_2O_3、或Nb_2O_5,以及AST剂(Al_2O_3、SiO_2和TiO_2)等,研制成功低电阻率(ρ≈10Ω.cm) 的PTCR热敏陶瓷产品。
The precursor for(Ba_xPb_(1-x) TiO_3)and(Ba_yPb_(1-y))TiO_3 are preparedthrough the oxalate and ammonate precipitation routes. A new type of PTCR ceramics with lowresistivity is developed, which is made into several devices and used in engine ignition andmedicine。
