鋯剛玉是以氧化鋁、氧化鋯為原料在電弧爐中經(jīng)2000℃以上高溫冶煉而成。鋯剛玉質(zhì)地堅(jiān)韌，結(jié)構(gòu)致密，強(qiáng)度高，熱穩(wěn)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.
鋯剛玉的分類：
鋯剛玉根據(jù)ZrO2的含量，一般有中鋯剛玉(ZrO2 25%)和高鋯剛玉(ZrO2 40%)。
