99% Al2O3 vacuum tube ceramic material and metallization method and application thereof
The invention discloses a 99% Al2O3 vacuum tube ceramic material and a metallization method and application thereof, and belongs to the technical field of metallization of alumina ceramics for vacuum arc extinguish chambers, 99% Al2O3 ceramics are adopted for ceramic metallization process research, and after the 99% Al2O3 ceramics are subjected to grinding, cleaning, glazing, glaze firing, pasting, primary metallization sintering, electroplating and secondary metallization sintering, the 99% Al2O3 ceramics are subjected to high-temperature metallization sintering to obtain the 99% Al2O3 vacuum tube ceramic material. Metallization is successfully achieved on 99% Al2O3 ceramic, after the 99% Al2O3 ceramic is metalized, the tensile strength of the 99% Al2O3 ceramic is far higher than that of 95% Al2O3 ceramic commonly used at home and abroad at present, the strength of the 99% Al2O3 ceramic after metallization and sealing is 1.2 times or above that of the 95% Al2O3 ceramic, and the metallization performance of the high-purity Al2O3 ceramic is improved, so that the voltage withstanding grade of a vacuum arc extinguish chamber is improved, and the service life of the vacuum arc extinguish chamber is prolonged. And a foundation is laid for the research of a miniaturized high-voltage vacuum arc-extinguishing chamber.
本发明公开了一种99％Al2O3真空管陶瓷材料及其金属化方法和应用，属于真空灭弧室用氧化铝陶瓷的金属化技术领域，采用99％Al2O3陶瓷进行陶瓷金属化工艺研究，99％Al2O3陶瓷经研磨，清洗，上釉，釉烧，涂膏，一次金属化烧结，电镀、二次金属化烧结后，成功在99％Al2O3陶瓷上实现了金属化，99％Al2O3陶瓷金属化后，其抗拉强度远高于目前国内外普遍使用的95％Al2O3陶瓷，其陶瓷金属化封接后的强度是95％Al2O3陶瓷的1.2倍以上，实现了高纯Al2O3陶瓷金属化性能的提升，从而提升了真空灭弧室的耐压等级，为小型化、高压真空灭弧室的研究做出铺垫。
