摘要
The improvement of anti-reduction properties for barium titanate base materials was studied by comparing the behavior of several kinds of ions in different sintering atmospheres. The results show that when sintered in a reducing atmosphere, both calcium and manganese ions can increase the insulating resistivity of the materials with the mechanism of acceptor dopants. The effect of manganese and zirconium on the Curie temperature was changed in different sintering atmospheres, which resulted from the valence state of the manganese ion and the proportion of substitution between Ti4+ and Mn2+. © 1990 IEEE
