This invention belongs to the field of ceramic equipment manufacturing technology, and discloses a metallized ceramic shell for a vacuum interrupter and its processing technology. The process uses low-sodium α-alumina with 0.5~1μm grain size as raw material, and acid washing improves its chemical purity and grain boundary stability. During granulation, the moisture content is controlled to ≤0.1%, and homogenization is used to remove iron and eliminate conductive impurities. A drying process is added between pressing and turning to improve processing precision. Through programmed temperature sintering combined with atmosphere control, the crystal structure is optimized and organic matter and gases are expelled, avoiding closed pore defects. After firing, polishing reduces surface roughness and prevents dust adsorption and conductivity. The glazing process uses bentonite and silica to adjust the glaze viscosity, ensuring uniform glaze coverage and matching the thermal expansion of the ceramic body, improving the outer surface insulation performance. The synergistic effect of each step comprehensively improves the purity, density, and surface quality of the ceramic shell, effectively meeting the stringent insulation strength requirements of high-voltage vacuum interrupters.
