Mg-Ti-O-based high-Q high-thermal-conductivity microwave dielectric ceramic material and preparation method thereof
The invention belongs to the technical field of electronic materials, and particularly relates to an Mg-Ti-O-based high-Q high-thermal-conductivity microwave dielectric ceramic material and a preparation method thereof. According to the ceramic material disclosed by the invention, a solid-phase reaction method is adopted, Mg2TiO4 is doped with TiO2 to generate a sub-crystalline phase MgTiO3 with a high Q value and a high heat conductivity coefficient, and the microstructure and density of the whole material are improved through a composite ceramic system, so that the heat conductivity and the Q * f value of the ceramic material are improved; according to the (1-y) Mg2TiO4 + yMgTiO3 ceramic material prepared by the invention, y is more than 0 and less than 0.5, the thermal conductivity is 8.0-10.5 W/(m.K), the Q * f value is 100000-150000 GHz, and the relative dielectric constant is 14-16. The Mg-Ti-O-based high-Q high-thermal-conductivity microwave dielectric ceramic material disclosed by the invention is simple in preparation process, has relatively high thermal conductivity and Q * f value and proper dielectric constant, and can be applied to the field of electronic packaging as a multilayer ceramic component material and a circuit substrate material.
