The sand is made of magnesite of super grade and first grade by light burning, fine grinding, ball pressing and sintering in high temperature shaft kiln. Magnesia has low impurity content, high bulk density and good slag resistance. It is used to manufacture intermediate grade magnesia or magnesia uncertain refractories.
