白剛玉是以優質的工業氧化鋁粉為原料，于電弧中經2000度以上高溫熔煉后冷卻制成，經破碎、磁選去鐵、篩分成各種粒度，它具有顏色潔白、硬度高、質地致密、純度高、自銳性優、磨削力強、發熱量小、效率高、耐酸堿腐蝕、耐高溫、熱穩定性好等特點，主要應用于中高檔定型和不定型耐火材料，也用于陶瓷制品、砂輪、研磨、拋光、噴砂、精密鑄造、鑄造涂料等行業。
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.
