Application of large crystalline fused magnesia

Large-crystal fused magnesia has high purity, large crystal grains, compact structure, strong slag resistance, and good thermal shock stability. It is an excellent high-temperature electrical insulating material, and also an important raw material for producing high-grade magnesia bricks, magnesia-carbon bricks and amorphous refractory materials. Large-crystal fused magnesia is a crystallization product made of super-grade magnesite after light burning and then cooled by electric furnace high-temperature melting. It is characterized by high content and low impurities, With the advantages of good transparency and full crystallization, it is the Z grade of ordinary large crystal products, mainly used in special precision casting, metallurgical bricks, new energy materials and other industries, and widely exported to all parts of the world. Large-crystal fused magnesium is mainly used for refractory materials, gunning materials, electric fusion ramming materials, furnace repair materials, coating materials, refractory mud, masonry materials, etc. It is a large-crystal fused sand made from pure natural high-purity light-burned magnesium powder and fired by 3000KVA electric fusion, and is a high-grade alkaline refractory material. It has the characteristics of high purity, good calcium to silicon ratio, large crystal particle size, stable physical and chemical properties, and is mainly used in metallurgy, chemical industry, electrical appliances, aerospace, national defense and other industrial fields.

Most manufacturers producing large-crystal fused magnesia supply high-quality 97/98 large-crystal fused magnesia. Large-crystal fused magnesia is produced by melting in electric arc furnace with selected special grade A natural magnesite or high-purity light-burned magnesia particles. This product has high purity, large crystal grain, compact structure, strong slag resistance and good thermal shock stability. It is an excellent high-temperature electrical insulation material, and also an important raw material for producing high-grade magnesia brick, magnesia-carbon brick and amorphous refractory.
