剛玉-莫來石坩堝是指由剛玉（a-Al₂O₃）和莫來石（3Al₂O₃·2SiO₂）兩種高溫物相共同構(gòu)成的復(fù)相耐火材料，將剛玉的高強(qiáng)度、高硬度、高耐火度性能與莫來石優(yōu)異的熱震性能和高溫蠕變性有機(jī)的結(jié)合在一起，通常Al₂O₃含量在75%-85%，比重通常在2.6-3.1g/cm³，最高使用溫度1700℃，對大多數(shù)金屬及合金具有良好的耐腐蝕性。

Corundum-mullite crucibles refers to a multiphase refractory material composed of two high-temperature phases: corundum (α-Al₂O₃) and mullite (3Al₂O₃·2SiO₂). It organically combines the high strength, high hardness, and high refractoriness of corundum with the excellent thermal shock resistance and high-temperature creep resistance of mullite. Typically, the Al2O3 content ranges from 75% to 85%, the specific gravity is 2.6-3.1 g/cm³, and the maximum operating temperature is 1700℃. It exhibits good corrosion resistance to most metals and alloys.
