Microwave dielectric ceramic material with high thermal shock resistance and preparation method thereof
The invention relates to the technical field of ceramic materials, and provides a microwave dielectric ceramic material with high thermal shock resistance. The microwave dielectric ceramic material with high thermal shock resistance comprises a ceramic main material, a modifier and a binder, the ceramic main material is selected from (1-x)MgTiO3.xSrTiO3, and x is 0.02-0.08. In terms of 100% of thetotal weight of the ceramic main material, the modifier accounts for 1-5% by weight of the ceramic main material, and the binder accounts for 0.5-3.0% by weight of the ceramic main material. The dielectric constant epsilon r of the ceramic is 19-21, the quality factor Q x f is 110000-130000 GHz, the temperature coefficient tau f of resonance frequency is -4 to 10 ppm/DEG C, and the thermal shocktemperature difference is 85-95 DEG C. Compared with a microwave dielectric ceramic material of an MgTiO3-CaTiO3 system, the quality factor Q x f and the thermal shock resistance are high under the condition of keeping the dielectric constant epsilon r of the ceramic unchanged.
