Low-temperature sintered microwave dielectric ceramic material and preparation method thereof
The invention provides a low-temperature sintered microwave dielectric ceramic material. The low-temperature sintered microwave dielectric ceramic material is prepared from the following formula components: (Mg < 1-x > Znx) < 2 + y > SiO4 + y + a wt% CaTiO3 + b wt% Zn-B-Si glass, wherein 0 < = x < = 0.5, 0 < = y < = 0.1, 5 < = a < = 20, and 3 < = b < = 15. The invention also provides a preparation method of the low-temperature sintered microwave dielectric ceramic material. The resonant frequency temperature coefficient of the microwave dielectric material is adjusted by adjusting the contents of (Mg1-xZnx) 2 + ySiO4 + y and CaTiO3, the dielectric material can be compactly sintered at the temperature below 900 DEG C by adding Zn-B-Si glass, and the finally obtained material has the characteristics of low dielectric constant, low loss and low temperature drift, and can be used for manufacturing LTCC filters, antennas, baluns and other products in the communication field.
本发明提供一种低温烧结微波介质陶瓷材料，其配方组分如下：(Mg1‑xZnx)2+ySiO4+y+a wt%CaTiO3+b wt%Zn‑B‑Si玻璃；其中，0≤x≤0.5，0≤y≤0.1，5≤a≤20，3≤b≤15。本发明还提供该低温烧结微波介质陶瓷材料的制备方法。本发明通过调整(Mg1‑xZnx)2+ySiO4+y和CaTiO3的含量，来调整微波介质材料的谐振频率温度系数，通过添加Zn‑B‑Si玻璃，使介质材料可以在900℃以下实现致密烧结，最终值得的材料具备低介电常数，低损耗，低温漂的特征，可用于制作通信领域LTCC滤波器、天线、巴伦等产品。
