Ultrahigh-purity aluminum oxide ceramic metallization method
The invention belongs to the technical field of electronic functional ceramic materials, and particularly relates to an ultrahigh-purity aluminum oxide ceramic metallization method. Aiming at the problems of low strength, poor heat conductivity, and poor air tightness of a ceramic matrix caused by an aluminum oxide ceramic metallization sintering process, the invention provides an ultrahigh-purityaluminum oxide ceramic metallization method. The method comprises the following steps: a, weighing raw material powder, dispersing the raw material powder into alcohol, ball-milling, and drying to prepare a metallized slurry additive; b, mixing molybdenum powder, molybdenum trioxide powder, manganese powder and the metallized slurry additive to obtain powder, and ball-milling the powder to obtainmetallized powder; c, subjecting the metallized powder to vibration grinding to obtain metallized slurry; and d, printing or coating the metallized slurry, and sintering to obtain a metallized product. The sintering temperature of the metallized slurry is lower than an existing sintering temperature, multiple times of metallized sintering can be achieved, the thickness of a metallized layer is increased, and after nickel plating, the metallized layer is good in stripping effect, high in stripping strength and good in metallized tensile strength performance.
本发明属于电子功能陶瓷材料技术领域，具体涉及一种特高纯氧化铝陶瓷金属化方法。针对氧化铝陶瓷金属化烧结过程导致的陶瓷基体强度低、热导率及气密性差等问题，本发明提供了一种特高纯氧化铝陶瓷金属化方法，包括以下步骤：a、称取原材料粉体，分散于酒精，球磨、烘干，制备金属化浆料添加剂；b、将钼粉、三氧化钼粉、锰粉、金属化浆料添加剂混合，得到粉料，球磨，制得金属化粉料；c、金属化粉料振磨，即得金属化浆料；d、将金属化浆料印刷或涂覆后烧结，得到金属化产品。本发明的金属化浆料烧结温度低于现有烧结温度，可多次金属化烧结，提高金属化层厚度，镀镍后，金属化层的剥离效果好，剥离强度高，金属化抗拉强度性能好。
