Low-temperature co-fired composite ceramic material and preparation method thereof
The invention relates to the field of microwave dielectric ceramics, in particular to a low-temperature co-fired composite ceramic material and a preparation method thereof. The technical problem to be solved by the invention is to provide the low-dielectric constant and high-quality factor low-temperature co-fired composite ceramic material with low cost and simple process and the preparation method thereof. The low-temperature co-fired composite ceramic material is prepared from the following main raw materials in percentage by weight: 30 to 60 percent of Al2O3, 0 to 30 percent of orthosilicate, 30 to 60 percent of low-melting-point glass and 0.1 to 10 percent of titanate ceramic. The preparation method of the low-temperature co-fired composite ceramic material comprises the following steps: adding water into the raw materials of the low-temperature co-fired composite ceramic material, performing ball milling, filtering, drying and dispersing obtained slurry to obtain low-temperature co-fired composite ceramic powder, and sintering the low-temperature co-fired composite ceramic powder to obtain the low-temperature co-fired composite ceramic material.
本发明涉及微波介质陶瓷领域，尤其涉及低温共烧复合陶瓷材料及制备方法。本发明所解决的技术问题是提供成本低、工艺简单的低介电常数高品质因数的低温共烧复合陶瓷材料及制备方法。该低温共烧复合陶瓷材料，主要原料以重量百分比计，包括：Al2O3 30～60％，正硅酸盐0～30％，低熔点玻璃30～60％，钛酸盐陶瓷0.1～10％。其制备方法为将上述低温共烧复合陶瓷材料的原料加水球磨后，获得的料浆过滤、干燥后分散，即得低温共烧复合陶瓷粉体，再将低温共烧复合陶瓷粉体烧结即可。
