主要是以氧化鋁和氧化鋯為成分復合而成的耐高溫材料，根據(jù)氧化鋯含量不同，一般分為25#、40#。體積密度一般在4.0g/cm3以上，最高使用溫度在1800℃，高溫穩(wěn)定性能強，可長期在1750℃正常使用；具有極高的熱穩(wěn)定性能，可在急冷急熱環(huán)境下，多次正常使用；同時具有耐熔體侵蝕性能和強機械性能。

It is primarily a high-temperature resistant material composed of a composite of alumina and zirconia. Depending on the zirconia content, it is generally classified as 25# and 40#. The bulk density is generally above 4.0g/cm3, with a maximum operating temperature of 1800℃. It exhibits strong high-temperature stability and can be used normally at 1750℃ for extended periods. It has extremely high thermal stability and can be used multiple times in rapid cooling and heating environments. Additionally, it possesses resistance to melt erosion and strong mechanical properties.
