Method for metalizing beryllium oxide ceramic
The invention belongs to the technical field of electronic functional ceramic materials, and in particular relates to a method for metalizing beryllium oxide ceramic. The technical problem solved by the invention is to provide the method for metalizing the beryllium oxide ceramic. The method comprises the following steps: A, preparing a metalizing sizing material additive by adopting raw materials of Al2O3, SiO2, CaCO3 and BaCO3 and a ball milling process; B, adding tungsten powder and manganese powder into the metalizing size additive, and performing ball milling to obtain metalizing powder; C, adding an active agent Y2O3 and a binding agent, and performing vibro-milling filtration to obtain a metallization sizing material; and D, performing metallization sintering. By adopting the metallization method provided by the invention, the sizing material sintering temperature is low, a single-sintering metallization layer is thick and can be sintered for multiple times, and energy consumption is reduced; moreover, the metallization layer after nickel plating has the characteristics of being good in stripping effect, high in stripping strength, high in tensile strength and the like, not only can meet metallization requirements of 99% of the beryllium oxide ceramic but also can meet requirements of 97% of beryllium oxide ceramic and beryllium oxide based attenuation ceramics, and is wide in application range.
