通过掺杂Ｎｂ＿２Ｏ＿５、Ｂｉ＿２Ｏ＿３、ＳｉＯ＿２等多种添加剂，研究了ＴｉＯ＿２电容、压敏复合功能材料。这种材料既有大电容特性，又有压敏电阻的功能。基于半导体陶瓷的双肖特基势垒模型，本文还从理论上对这种复合功能材料的压敏、电容特性进行了分析，得到的非线性系数和表现介电常数的理论值能较好地与实验结果相一致。本文的实验结果与理论分析对于进一步研究功能陶瓷材料等具有十分重要的意义。
By doping Nb_2O_5, Bi_2O_3, SiO_2 and other additives, the study of the TiO_2 capacitance, pressure-sensitive composite materials. This material has both large capacitance characteristics, but also varistor function. Based on the double Schottky barrier model of semiconductor ceramics, the pressure-sensitive and capacitive characteristics of the composite functional material are also theoretically analyzed. The theoretical values of the nonlinear coefficient and the permittivity can be obtained well Consistent with the experimental results. The experimental results and theoretical analysis of this paper are of great significance for the further study of functional ceramic materials.
