What is the refractory temperature of magnesia?

What is the refractory temperature of magnesia? Magnesite can be divided into 5 types; 1. Reburned magnesia, 2. Medium grade magnesia, 3. High purity magnesia, 4. Electric fused magnesia, 5. Large crystal electric fused magnesia, and the following sections will introduce the fire resistance temperatures of the five types of magnesia. 1. The fire resistance temperature of reburned magnesia can reach more than 1600 ℃, 2. The fire resistance temperature of medium grade magnesia can reach more than 1800 ℃, and 3. The fire resistance temperature of high purity magnesia can reach more than 2000 ℃, The refractory temperature of fused magnesia can reach more than 2200 ℃, and the refractory temperature of large crystalline fused magnesia can reach more than 2400 ℃. Magnesia is an alkaline refractory raw material, and the main component of the product is Mgo magnesium oxide. Magnesia is widely used in metallurgy, chemical industry, national defense, scientific research, aerospace, household electrical components and other industries.
