| Abstract: | A method of making a kind of ceramic powder was introduced that has a negative line-type TC(temperature coefficient) curve.Modification effect on SrTiO3 system by using Bi3+、Pb2+ and CuO were studied.This capacitor ceramic powder can be sintered at 1 300 ℃,and meet N4700 TC standard,whose main specifications are as follows: εr>2 500,tanδ≤0.05 %,ΔC–40℃/C20℃>25.2 % andΔC+80℃/C20℃<–25.2 %. |
