Alumina-based composite ceramic dielectric layer and preparation method thereof
The invention relates to an alumina-based composite ceramic dielectric layer. The alumina-based composite ceramic dielectric layer is composed of a silicon carbide whisker toughened alumina-based composite ceramic layer and a modified organic silicon resin surface coating. The invention also provides a preparation method of the alumina-based composite ceramic dielectric layer, which comprises the following steps: carrying out wet ball-milling dispersion on raw materials to prepare mixed slurry, carrying out casting, silk-screen printing, laminating and sintering processes to obtain alumina-based composite ceramic, leveling and polishing the surface of the alumina-based composite ceramic, carrying out sand blasting to control the roughness, and then spraying the modified organic silicon resin to obtain the alumina-based composite ceramic dielectric layer. And the alumina-based composite ceramic dielectric layer is obtained. The silicon carbide whiskers are creatively introduced, the mechanical property of the aluminum oxide-based composite ceramic dielectric layer is improved, the mechanical strength and thermodynamic stability of the aluminum oxide-based composite ceramic dielectric layer are improved by doping a small amount of aluminum nitride, the surface etching resistance is improved by spraying the modified organic silicon resin, and the service life is prolonged.
本发明涉及一种氧化铝基复合陶瓷介电层，由碳化硅晶须增韧的氧化铝基复合陶瓷层与改性有机硅树脂表面涂层组成。本发明还提供一种氧化铝基复合陶瓷介电层的制备方法，包括如下步骤：将原料湿法球磨分散制备混合料浆，再经流延、丝网印刷、叠层、烧结工艺，得到氧化铝基复合陶瓷，其表面整平抛光后，喷砂控制粗糙度，再喷涂改性有机硅树脂，即得氧化铝基复合陶瓷介电层。本发明创造性地引入碳化硅晶须，提高氧化铝基复合陶瓷介电层的力学性能，少量掺入氮化铝提高其力学强度与热力学稳定性，喷涂改性有机硅树脂提高表面抗蚀刻性能，延长使用寿命。
