Silicate microwave dielectric ceramic material and preparation method thereof
The invention relates to an electronic ceramic material, in particular to a silicate microwave dielectric ceramic material and a preparation method thereof. The silicate microwave dielectric ceramic material is prepared from the following materials in parts by mass: 100 parts of a base material, 2-6 parts of an auxiliary material, and 2-10 parts of a sintering aid; the chemical composition expression of the base material is Ca1-x Sr x MgSi2O6, wherein x is greater than or equal to 0.1 and less than or equal to 0.6; the auxiliary material is SrTiO3; the sintering aid is LiF. The silicate microwave dielectric ceramic material provided by the invention is low in dielectric constant, low in dielectric loss and good in high-temperature stability, the relative dielectric constant epsilon r is adjustable in the range of 7.30-7.78, the Q * f value is 18271-46840 GHz, the temperature coefficient of resonance frequency tau f is adjustable in the range of -22.6- + 7.3 ppm/DEG C; and the silicate microwave dielectric ceramic material can become a new LTCC material; and therefore, the material can be widely applied to LTCC microwave substrates, laminated microwave devices and modules.
本发明涉及一种电子陶瓷材料，尤其是一种硅酸盐微波介质陶瓷材料及其制备方法。一种硅酸盐微波介质陶瓷材料，由以下材料按照质量份数制成：基料100份；辅助料2～6份；烧结助剂2～10份；其中，所述基料的化学组成表达式为Ca1‑xSrxMgSi2O6，其中0.1≤x≤0.6；所述辅助料为SrTiO3；所述烧结助剂为LiF。本发明提供的一种硅酸盐微波介质陶瓷材料低介电常数、低介电损耗、高温度稳定性好，相对介电常数εr在7.30～7.78范围可调，Q×f值为18271～46840GHz，谐振频率温度系数τf在‑22.6～+7.3ppm/℃范围可调，可以成为一种新的LTCC材料，从而可以广泛应用于LTCC微波基板、叠层微波器件和模块中。
