主要化學(xué)成分Al₂O₃，純度高達99%，體積密度一般在3.0-3.3g/cm³。可長期穩(wěn)定在1750℃下使用，具有優(yōu)異的耐高溫性能、良好的熱穩(wěn)定性性能和化學(xué)惰性，對貴金屬、鐵、鈷、鎳

基合金等金屬及酸性環(huán)境都有很強的抗腐蝕性。

The main chemical component is Al₂O₃, with a purity of up to 99% and a bulk density generally ranging from 3.0 to 3.3g/cm³. It can be stably used at 1750℃ for a long time, exhibiting excellent high-temperature resistance, good thermal stability, and chemical inertness. It also has strong corrosion resistance to precious metals, iron, cobalt, nickel-based alloys, and acidic environments.
