Explosion-proof ceramic material and preparation method thereof

The invention discloses an explosion-proof ceramic material. The explosion-proof ceramic material comprises the following components in parts by weight: 10 to 15 parts of titanium dioxide, 7.5 to 12 parts of zirconium dioxide, 7.5 to 12 parts of manganese dioxide, 2 to 10 parts of zinc dioxide, 1.5 to 8 parts of tungsten oxide, 55 to 75 parts of aluminum oxide, 2 to 8 parts of calcium stannate, 3 to 10 parts of ferric oxide and 3 to 10 parts of magnesium titanate. By adjusting a formula of the explosion-proof ceramic material, an aluminum oxide ceramic piece prepared from the novel material has the same strength as aluminum oxide ceramic and also has excellent explosion-proof performance. The material has good adsorbability to a coating on the surface of ceramic, and is an ideal material for high-power and high-current ceramic tubes. 本发明公开了一种防爆陶瓷材料，包括以下重量组分的各组成成分：二氧化钛10～15份、二氧化锆7.5～12份、二氧化锰7.5～12份、二氧化锌2～10份、氧化钨1.5～8份、三氧化二铝55～75份、锡酸钙2～8份、三氧化二铁3～10份、钛酸镁3～10份。通过调整防爆陶瓷材料的配方，使得用上述新材料制成的氧化铝陶瓷件既具有氧化铝陶瓷的强度，又具有优秀的防爆性能
