Microwave dielectric ceramic material and preparation method thereof
The invention relates to the technical field of ceramic materials, and provides a microwave dielectric ceramic material which comprises titanium dioxide, lanthanum oxide, a lithium-containing compound and a boron-containing compound. The titanium dioxide and the lithium-containing compound interact to generate a titanium-lithium phase; the lanthanum oxide and the boron-containing compound interact to generate a lanthanum-boron phase, the generated titanium-lithium phase and the lanthanum-boron phase can be sintered at the temperature lower than 900 DEG C to obtain the microwave dielectric ceramic material, the sintering temperature is low, a sintering aid does not need to be used, and the obtained microwave dielectric ceramic material is stable in structure, high in compactness, and high in quality factor The temperature coefficient of resonance frequency is close to zero, and wide application is facilitated.
本申请涉及陶瓷材料技术领域，提供了一种微波介质陶瓷材料，该材料中包括二氧化钛、氧化镧、含锂化合物和含硼化合物，其中，二氧化钛与含锂化合物相互作用生成钛‑锂相；氧化镧与含硼化合物相互作用生成镧‑硼相，生成的钛‑锂相和镧‑硼相可在低于900℃的温度下进行烧结得到微波介质陶瓷材料，烧结温度低，且不需要使用烧结助剂，同时得到的微波介质陶瓷材料结构稳定，致密性强，品质因数高，谐振频率温度系数接近于零，有利于广泛应用。
