Borate-based low-dielectric microwave dielectric ceramic and preparation method thereof
The invention discloses borate-based low-dielectric microwave dielectric ceramic and a preparation method thereof, the chemical composition of the microwave dielectric ceramic is CaB<2>O<3+x>, and x is more than or equal to 0.3 and less than or equal to 3.0. The dielectric constant of the microwave dielectric ceramic ranges from 5.62 to 10.12, the quality factor ranges from 13161 GHz to 52416 GHz, and the temperature coefficient of resonance frequency ranges from-20.42 ppm/DEG C to-54.65 ppm/DEG C. The microwave dielectric ceramic is obtained by heating to 700 DEG C at a speed of 5 DEG C/min, preserving heat for 3 hours to finish presintering synthesis, heating to 750-1275 DEG C at a speed of 5 DEG C/min, and preserving heat for 3 hours to finish sintering. The microwave dielectric ceramic prepared in the invention has the advantages of low dielectric constant, high quality factor and low sintering temperature, and is suitable for preparing LTCC substrates, dielectric resonators, filters, dielectric antennas and other microwave communication devices.
