[0002] Refractory materials refer to materials that can stably exist at high temperatures (not less than 1580℃) and resist thermal expansion, thermal shock and chemical erosion. Refractory materials are widely used in metallurgy, chemical industry, petroleum, machinery manufacturing, silicate, power and other industrial fields. In the manufacturing process of refractory materials, after the materials of different particle sizes are graded, the most dense stacking can be ensured to obtain a dense refractory embryo.
