description The invention relates to a multiphase conductive ceramic material. The material is mainly prepared from, by weight, 50-75% of calcined aluminum oxide, 5-40% of tin dioxide, 5-10% of silicon dioxide, 3-6% of magnesium oxide, 2-5% of calcium oxide, 0.05-0.6% of antimony trioxide, 0.01-0.1% of zinc oxide and 0.01-0.1% of copper oxide. The ceramic material is good in electrical conductivity, small in density, high in strength and small in thermal expansion coefficient and is an excellent choice for manufacturing the substrate of the working table of the scribing equipment, the manufacturing process is simplified due to the whole-body electrical conductivity, and the service life of the working table is prolonged; and the ceramic material is also suitable for electrical discharge machining and is applied to other conductive and anti-static fields. 本发明涉及一种复相导电陶瓷材料,其主要由下述重量百分比原料制成:煅烧氧化铝50-75%,二氧化锡5-40%,二氧化硅5-10%,氧化镁3-6%,氧化钙2-5%,三氧化二锑0.05-0.6%,氧化锌0.01-0.1%,氧化铜0.01-0.1%。该陶瓷材料导电性良好,密度小,强度高,热膨胀系数小,是制作划片设备工作台基座的极佳选择,通体导电
