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成的復相耐火材料，將剛玉的高強度、高硬度、高耐火度性能與莫來石優異的熱震性能和高溫蠕變性有機的結合在一起，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.
