一种Ti基LTCC微波介电陶瓷材料及其制备方法
摘要：
本发明属于电子陶瓷材料及其制造领域，具体涉及一种Ti基LTCC微波介电陶瓷材料及其制备方法。本发明首先将(Mg0.95Co0.05)2TiO4与Li2TiO3进行复合，然后再借助LMZBS玻璃掺杂助熔来实现整个材料体系的900～950℃低温烧结。最终实现在900℃低温烧结下最佳性能可达到介电常数：εr＝16.6,Q×f＝125800GHz，τf＝1.4ppm/℃。本发明兼具超低损耗、近零谐振频率温度系数以及低温烧结的高性能，其介电常数εr为16.6～17.1，Q×f值为88400～125800GHz，谐振频率温度系数τf为1.3～5.1ppm/℃。可广泛应用于LTCC微波基板、叠层微波器件和模块中。
摘要（英）：

The invention belongs to an electronic ceramic material and the manufacturing field thereof, and in particular relates to a Ti-based LTCC microwave dielectric ceramic material and a preparation method thereof. The preparation method comprises the following steps: firstly, compounding (Mg0.95Co0.05)2TiO4 and Li2TiO3; then realizing low-temperature sintering at 900-950 DEG C of a whole material system by means of LMZBS glass doped fluxing; and finally, realizing the optimum properties under the low-temperature sintering at 900 DEG C: the dielectric constant: epsilonr=16.6, Q*f=125800GHz and tauf=1.4ppm/DEG C. The Ti-based LTCC microwave dielectric ceramic material provided by the invention has high properties of ultra-low-loss, near-zero temperature coefficient of resonance frequency and low-temperature sintering. The dielectric constant of the material epsilonr is 16.6-17.1, the Q*f value is 88400-125800GHz, and the temperature coefficient of resonance frequency tauf is 1.3-5.1ppm/DEG C. The material can be widely applied to an LTCC microwave substrate, a laminated microwave apparatus and a module.
