鎂鋁尖晶石坩堝是以方鎂石和尖晶石為主要礦化物的堿性耐火材料，同時添加優質的礦化物，使制品晶相顆粒之間緊密結合，經高壓成型，高溫燒結而成。體積密度一般在3.2g/cm³以上，最高使用溫度1750℃。具有強度高，抗熱震性能的優點，對于堿性環境有極高的抗腐蝕性。

Magnesia-alumina spinel crucibles are alkaline refractory materials primarily composed of periclase and spinel, with the addition of high-quality mineralizers to ensure tight binding between the crystal grains of the product. They are formed through high-pressure molding and high-temperature sintering. The bulk density is generally above 3.2g/cm³, and the maximum operating temperature is 1750℃. They possess advantages such as high strength and thermal shock resistance, and exhibit excellent corrosion resistance in alkaline environments.
