Microwave dielectric ceramic material with low expansion coefficient, and preparation method thereof
The invention is applicable to the technical field of dielectric ceramic production, and discloses a microwave dielectric ceramic materialwith a low expansion coefficient. The material comprises a main component and a modified additive, the main component is xAl2O3-yTiO2, x = 0.88-0.92, y = 0.06-0.09; and the modified additive is a combination of at least two of ZrO2, La2O3, Nd2O3, SiO2 and CaCO3. The invention also provides a method for preparing microwave dielectric ceramic material with the low expansion coefficient. The microwave dielectric ceramic material with the low expansion coefficient has the advantages of low expansion coefficient, adjustable dielectric constant, high quality factor and near-zero temperature coefficient of resonance frequency.
本发明适用于介质陶瓷生产技术领域，公开了一种低膨胀系数微波介质陶瓷材料，包括主体成分和改性添加剂，所述主体成分为xAl2O3‑yTiO2，其中x＝0.88‑0.92，y＝0.06‑0.09；所述改性添加剂为ZrO2，La2O3、Nd2O3、SiO2、CaCO3中的至少两个的组合。还提供了一种制备所述低膨胀系数微波介质陶瓷材料的方法。本发明的低膨胀系数微波介质陶瓷材料具有低膨胀系数、介电常数可调、高品质因数和近零的谐振频率温度系数的优点。
