More Information
Summary:The invention provides a microwave dielectric ceramic composite material and a preparation method thereof, and relates to the technical field of electronic ceramic components and materials for wireless mobile communication and radio frequency electronic circuit systems. The microwave dielectric ceramic composite material is a composite material of a cordierite crystal structure material doped with Zn<2+> and Mn<4+> and TiO2, and Al<3+> in cordierite crystal lattices is synergistically replaced by Zn<2+> and Mn<4+>. The invention also provides the microwave dielectric ceramic composite material and a preparation method thereof. The sintering temperature of the composite material prepared by the preparation method is 1225 DEG C to 1350 DEG C, the dielectric constant is 5.12 to 5.82, the quality factor is 47026 GHz to 81609 GHz, and the temperature coefficient of resonance frequency is + 2.43 ppm/DEG C to -26.84 ppm/DEG C. According to the composite material, the sintering densification temperature of various ex
