[Abstract]:Microwave sintered dielectric ceramics were prepared by microwave sintering. The sintering properties and microstructure of MZT-CLT ceramics by microwave sintering were studied. The results show that the main crystalline phase of MZT-CLT ceramics is: the main crystal phase of the MZT-CLT ceramics is: the main crystal phase of the MZT-CLT ceramics is: the main crystal phase of the MZT-CLT ceramics is: the main crystal phase of the MZT-CLT ceramics is: the main crystal phase of the MZT-CLT ceramics is: the main crystal phase of the MZT-CLT ceramics is MZT-CLT, the main crystal phase of the MZT-CLT ceramics is: the main crystal phase of the MZT-CLT ceramics is: the main crystal phase of the MZT-CLT ceramics is: the main crystal phase of the MZT-CLT ceramics is: the main crystal phase of the MZT-CLT ceramics is. The microwave dielectric properties of the ceramics are as follows: dielectric constant 蔚 rn 26.21, the product of quality factor and frequency Q 路fN 120000GHz, and the frequency temperature coefficient 蟿 fn-3 脳 10 ~ (-1) ~ (-6) ~ (-1) / 鈩，
