Abstract: This paper presents a high frequency hot-steady and hot-compensatory ceramic materials for capacitor,which is mainly composed of CaTiSiO5-TiO2.By requlating percent content of CaTiSiO5 and TiO2, selecting WO3 and ZnO to be additives, controlling rationaliy sintering temperature, and presintering in suitable temperature, the excellent ceramic materials for high frequency capacitor are got.The dielectric constant is higher than country standard,many groups are up to ten by temperature coefficient, wide range of sintering temperature is up to 20℃.It also has good and repeatable procedure condition and low cost.
