Microwave dielectric ceramic material with low dielectric constant as well as preparation method and application of microwave dielectric ceramic material
The invention relates to a low-dielectric-constant microwave dielectric ceramic material and a preparation method and application thereof, the expression of the low-dielectric-constant microwave dielectric ceramic material is (1-q) LaxBySizO (1.5 x + 1.5 y + 2z) + qTiO2, 0 < = q < = 0.05, 0.9 < = x < = 1.1, 1.0 < = y < = 1.2, and 1.0 < = z < = 1.2. The low-dielectric-constant microwave dielectric ceramic material can be sintered into ceramic within the range of 1000-1200 DEG C, has a low sintering temperature and a wide sintering range interval, takes LaBSiO5 as a main crystal phase, has the characteristics of low dielectric constant, high quality factor and near-zero temperature coefficient of resonance frequency, and meets actual application requirements.
本发明涉及一种低介电常数微波介质陶瓷材料及其制备方法和应用，所述低介电常数微波介质陶瓷材料的表达式为：(1‑q)LaxBySizO(1.5x+1.5y+2z)+qTiO2，其中，0≤q≤0.05，0.9≤x≤1.1，1.0≤y≤1.2，1.0≤z≤1.2。本发明低介电常数微波介质陶瓷材料能够在1000℃～1200℃的范围内烧结成瓷，具有较低的烧结温度且烧结范围区间宽，并以LaBSiO5为主晶相，具有低介电常数、高品质因数以及近零谐振频率温度系数的特性，满足实际的应用需求。
