鋯剛玉是以天然鋯、鋁礬土、助溶劑為原料，經電弧爐2650℃以上高溫熔煉急冷結晶而成，其質地堅韌，微晶結構致密，強度高，熱物理性能好，廣泛用于制造高性能的磨料磨具和耐火材料制品。
Zirconia Fused Alumina is produced by fusing natural zirconium, bauxite, complex solubilizer in electric arc furnace, smelted with high temperature above 2650℃, cooling down with special technology, which has the characteristics of tenacious texture, dense structure and high strength and good thermophysical characterisics. It is widely used in the production of high quality abrasive and grinding tools and refractory products.
