Low-dielectric-loss microwave electronic ceramic material
The invention discloses a low-dielectric-loss microwave electronic ceramic material of which the expression is aZnO. bSiO2.cTiO2.dCaCO3.eAl2O3, wherein a, b, c, d and e respectively independently represent molar rates; and 35mol%<=a<=45mol%, 30mol%<=b<=35mol%, 0mol%<=c<=10mol%, 10mol%<=d<=20mol%, 0mol%<=e<=10mol%, and a+b+c+d+e=100mol%. The dielectric constant of the low-dielectric-loss microwave electronic ceramic material is 7-10; the low-dielectric-loss microwave electronic ceramic material has low loss (Qf is greater than 100000 GHz) and approximately zero temperature coefficient of resonance frequency; and by using the low-dielectric-loss microwave electronic ceramic, the dielectric resonator, filter and other microwave components can be more suitable for application in higher frequency and higher power, thereby being beneficial to improvement of the frequency and temperature stability of the device.
