What is the fire resistance temperature of medium grade magnesia?

Magnesia can be mainly divided into 5 types; 1. "Heavy burned magnesia, 2. Medium grade magnesia, 3. High purity magnesia, 4. Electric fused magnesia, 97 electric fused magnesia, 5. Large crystal electric fused magnesia, and the following brief introduction will introduce the respective fire resistance temperatures of the five types of magnesia. 1. The fire resistance temperature of heavy burned magnesia can reach 1600 ℃ or above, 2. The fire resistance temperature of medium grade magnesia can reach 1800 ℃ or above, and 3. The fire resistance temperature of high purity magnesia can reach 2000 ℃ or above.", The refractory temperature of fused magnesia can reach over 2200 ℃, and the refractory temperature of large crystalline fused magnesia can reach over 2400 ℃. Magnesia is an alkaline refractory raw material, and the main component of the product is Mgo magnesium oxide. Magnesia is widely used in industries such as metallurgy, chemical industry, national defense, scientific research, aerospace, and household electrical components. Fused magnesia
