白刚玉是以优质的工业氧化铝粉为原料，于电弧中经2000度以上高温熔炼后冷却制成，经破碎、磁选去铁、筛分成各种粒度，它具有颜色洁白、硬度高、质地致密、纯度高、自锐性优、磨削力强、发热量小、效率高、耐酸碱腐蚀、耐高温、热稳定性好等特点，主要应用于中高档定型和不定型耐火材料，也用于陶瓷制品、砂轮、研磨、抛光、喷砂、精密铸造、铸造涂料等行业。
White fused alumina is mainly refined with the high-quality industrial alumina powder as the main raw material, melted in the electric arc furnace with over 2000 ℃ high temperature before cooling. After crushing and magnetic separation of iron to sieve into a variety of granularity, the white fused alumina has pure white color with high hardness, high purity, excellent self-sharpening, high efficiency, acid and alkali corrosion, high temperature resistance, good thermal stability, which is mainly applied in the production of medium and high quality shaped and unshaped refractory materials, also widely used in ceramics, grinding wheels, polishing, sandblasting, precision casting, casting coatings, insulation materials and other industries.
