Composition, Structure And Properties Of Medium Magnesia

- Oct 11, 2018 -

Medium-grade magnesia is widely used to produce magnesia-carbon bricks, alumina-magnesia-carbon bricks, magnesia-alumina spinel bricks and other basic magnesia products because of its good resistance to alkaline slag corrosion. Through the study and analysis of volume density, apparent porosity and microstructure of sintered magnesia, the relationship between microstructure and macroscopic properties of sintered magnesia can be understood systematically. China produces 18 million tons of magnesite and 10 million tons of magnesia annually, accounting for about 80% of the world's Magnesia output. Magnesite production is mainly composed of sintering and electrofusion.
