High Purity Magnesite is selected from natural supergrade magnesia material and purified by flotation, then made by light burning, fine grinding, pressure ball, and calcined in an ultra-high temperature oil shaft kiln. It is a high-quality raw magnesia material for brick-making and amorphous refractories.
