Magnesia can be divided into 5 main types; 1, heavy-burned magnesia, 2, mid-range magnesia, 3, high-purity magnesia, 4, fused magnesia, 97 fused magnesia, 5, large crystalline fused magnesia, small below I will introduce you to the refractory temperature of the 5 kinds of magnesia. 1. The refractory temperature of the reburned magnesia can reach above 1600℃. 2. The refractory temperature of the mid-grade magnesia can reach above 1800℃. 3. The refractory temperature of high-purity magnesia. The temperature can reach above 2000℃, the refractory temperature of fused magnesia can reach above 2200℃, the refractory temperature of large crystal fused magnesia can reach above 2400℃, magnesia is an alkaline refractory raw material, the main component of the product is Mgo magnesium oxide , Magnesia is widely used in metallurgy, chemical industry, national defense, scientific research, aerospace, household appliances components and other industries.
