Low-dielectric and low-loss Ca-Al-B-based LTCC material and preparation method thereof
The invention belongs to the field of electronic ceramics and manufacturing thereof, and relates to a low-dielectric and low-loss Ca-Al-B-based microwave dielectric LTCC material and a preparation method thereof. The typical representative CaAl2B2O7 of a CaO-Al2O3-B2O3 ternary system is used as a Ca-Al-B-based microwave dielectric ceramic material and can be applied to the field of LTCC by addingan auxiliary agent, low-temperature compact sintering at 850-900 DEG C is realized, the dielectric constant is 5-6.2, the loss is reduced to 4.19*10<-4>, and the frequency temperature coefficient is -30--20 ppm/DEG C. CaAl2B2O7 is used as the typical representative of the CaO-Al2O3-B2O3 ternary system, the research of CaAl2B2O7 is only limited to luminescent property and crystal structure analysis, and in solid-phase sintering, the reaction process, the phase composition and the relationship between the microwave dielectric property and the content of each phase are not specifically researched. The invention provides a new choice of an LTCC material with excellent performance for the low-dielectric low-loss LTCC material.
本发明属于电子陶瓷及其制造领域，涉及一种低介电常数、低介电损耗Ca‑Al‑B基微波介质LTCC材料及其制备方法。本发明将CaO‑Al2O3‑B2O3三元体系的典型代表CaAl2B2O7作为Ca‑Al‑B基微波介质陶瓷材料通过添加助剂使其可应用于LTCC领域，实现了850℃～900℃的低温致密烧结，介电常数5～6.2，损耗低至4.19×10‑4，频率温度系数‑30～‑20ppm/℃。CaAl2B2O7作为CaO‑Al2O3‑B2O3三元体系的典型代表，其研究仅限于发光性能以及晶体结构分析，在固相烧结中，其反应过程、物相组成以及微波介电性能与各个物相含量之间的关系均未具体研究。本发明为低介低损LTCC材料提供了一种具有优异性能LTCC材料的新选择。
