Barium titanate-based two-phase composite microwave dielectric ceramic material and preparation method thereof
The invention belongs to the technical field of microwave dielectric ceramic materials, particularly relates to a barium titanate-based two-phase composite microwave dielectric ceramic material, and further discloses a preparation method of the barium titanate-based two-phase composite microwave dielectric ceramic material. The invention discloses the barium titanate-based two-phase composite microwave dielectric ceramic material; BaTiO3 and TiO2 are directly used as raw materials for preparation, and the dielectric constant of the obtained microwave dielectric ceramic material reaches 36-40,f * Q at 25 DEG C is larger than 20000, the frequency temperature coefficient calculated by testing the resonant frequencies f at-40 DEG C, 25 DEG C and 110 DEG C is low and is only-3 ppm/DEG C to 3 ppm/DEG C and close to zero, and the performance of the microwave dielectric ceramic material meets the requirements of microwave dielectric ceramic devices. Meanwhile, the material also has relativelygood dielectric property in a millimeter wave frequency band; the ceramic material can be used for producing ceramic devices such as filters and resonators, and has the advantages of easiness in synthesis of ceramic bodies and low manufacturing cost.
本发明属于微波介质陶瓷材料技术领域，具体涉及一种钛酸钡基两相复合微波介质陶瓷材料，并进一步公开其制备方法。本发明所述钛酸钡基两相复合微波介质陶瓷材料，直接以BaTiO和TiO为原料进行制备，得到的微波介质陶瓷材料的介电常数达到36‑40，25℃的f*Q＞20000，通过测试‑40℃、25℃、110℃的共振频率f计算出的频率温度系数较低，仅为‑3～3ppm/℃，接近于零，其性能符合微波介质陶瓷器件的要求；同时，材料在毫米波频段下也具有较好的介电性能；可以用于生产滤波器和谐振器等陶瓷器件，且具有易合成陶瓷体、制造成本低的优势。
