镁砂主要可以分为5种：重烧镁砂、中档镁砂、高纯镁砂、电熔镁砂、大结晶电熔镁砂。97电熔镁砂，下面小编为你介绍镁砂分别的耐火温度是多少：

1、重烧镁砂的耐火温度可以达到1600℃以上，

2、中档镁砂的耐火温度可以达到1800℃以上，

3、高纯镁砂的耐火温度可以达到2000℃以上，电熔镁砂的耐火温度可以达到2200℃以上，大结晶电熔镁砂的耐火温度可以达到2400℃以上，镁砂属于碱性耐火原料，产品主要成分是Mgo氧化镁，镁砂广泛应用于冶金、化工、国防、科研、航天航空、家用电器元件等行业使用。

Magnesia sand can be mainly divided into 5 types: heavy burned magnesia sand, medium magnesia sand, high-puritynesia sand, electric fused magnesia sand, and large crystalline electric fused magnesia sand. The refractoriness of 97% electric fused magnesia sand reach above 1600℃, the refractoriness of medium magnesia sand can reach above 1800℃, the refractoriness of high-urity magnesia sand can reach above 2000℃, the refractoriness of electric fused magnesia sand can reach above 2200℃, the refractoriness of large crystalline electric fused magnesia sand can reach above 2400℃. Magnesia sand belongs to alkaline refractory raw materials and the main component of the product is Mgo magnesium oxide. Magnesia sand is widely used in metallurgy, chemical industry, national defense, scientific research, aerospace, household appliances and other industries.
