锆刚玉是以氧化铝、氧化锆为原料在电弧炉中经2000℃以上高温冶炼而成。锆刚玉质地坚韧，结构致密，强度高，热稳定性好，一般呈灰褐色。
Fused Zirconia Alumina,was made from alumina and Zirconium oxide by melting above 2000 in the electric arc furnace and rong but pliable in texture,compact structure,Good Thermal Stability.generally it is gray color.
锆刚玉的分类：
锆刚玉根据ZrO2的含量，一般有中锆刚玉(ZrO2 25%)和高锆刚玉(ZrO2 40%)。
