镁铝尖晶石坩埚是以方镁石和尖晶石为主要矿化物的碱性耐火材料，同时添加优质的矿化物，使制品晶相颗粒之间紧密结合，经高压成型，高温烧结而成。体积密度一般在3.2g/cm³以上，最高使用温度1750℃。具有强度高，抗热震性能的优点，对于碱性环境有极高的抗腐蚀性。

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.
