ABO4型稀土铌/钽酸盐LTCC材料及其制备方法
本发明属于电子陶瓷及其制造领域，涉及ABO4型稀土铌/钽酸盐LTCC材料及其制备方法。本发明提供的LTCC材料包括基料为ABO4型稀土铌/钽酸盐陶瓷和占基料质量百分比为2.5～15wt％的降烧剂,降烧剂随着温度升高而熔化产生液相。液相烧结过程能够大幅降低ABO4型稀土铌/钽酸盐的烧结温度，使陶瓷材料在875～950℃下烧结致密。本发明所制备的LTCC材料介电常数为5～20，品质因数可高达27466GHz，频率温度系数‑50～‑5ppm/℃，能够应用在介质基板、滤波器等LTCC电子元器件中。
The invention belongs to the field of electronic ceramics and manufacturing thereof, and relates to an ABO4 type rare earth niobium/tantalate LTCC material and a preparation method thereof. The LTCC material provided by the invention comprises ABO4 type rare earth niobium/tantalate ceramic serving as a base material and a burning reducing agent accounting for 2.5-15 wt% of the base material, wherein the burning reducing agent is melted along with temperature rise to generate a liquid phase. The sintering temperature of ABO4 type rare earth niobium/tantalate can be greatly reduced in the liquid-phase sintering process, so that the ceramic material is sintered compactly at 875-950 DEG C. The dielectric constant of the prepared LTCC material is 5-20, the quality factor can reach up to 27466 GHz, the frequency temperature coefficient is-50 to-5 ppm/DEG C, and the LTCC material can be applied to LTCC electronic components such as dielectric substrates and filters.
