High purity magnesia refers to high-purity magnesia with a magnesium oxide content of over 96%, which is obtained by using natural high-grade magnesite ore for flotation purification, light burning, fine grinding, ball pressing, and ultra-high temperature oil vertical kiln calcination.
High purity magnesia sand is mainly used for high-purity magnesia bricks, directly combined with magnesia chrome bricks, spraying materials for converters and electric furnaces, large-area repair materials for converters, and spraying materials for intermediate packages.
