Abstract
A composite dielectric ceramic material having anti-reduction and high temperature stability characteristics includes the main component of (1-x)(BaTiO)-x(BaLiTaO) formulated in accordance with the relative molar ratio of up to 100 mole composite dielectric ceramics and a predetermined ratio of one or multiple oxide subcomponents corresponding to 100 moles of the main component. The oxide subcomponents of LiTiO, BaSiO, (BaCa)SiOand SiOcan be used as sintering aids to provide a sintering promotion effect. The oxide subcomponents of CaO, MnO, MgO can also be selected used to improve dielectric stability. More particularly, CaO has the advantages of improving the anti-reduction ability and increasing the coefficient of resistance. Therefore, with the adding of the oxide subcomponents and their interactions, the rate of change of the TCC curve of the composite dielectric ceramic material (1-x)(BaTiO)-x(BaLiTaO) in the temperature range of −55° C.˜200° C. is significantly inhibited, and its dielectric constant (k-values) is also well improved.
