Dead Burned Magnesite is made of high quality magnesite, which is flotation and concentration, briquetting, calcination, high temperature sintering method and fired in vertical kiln, with high MgO content, low Apparent Porosity and high Bulk Densitey. It is an excellent raw material for making bricks and molding whole refractory products.
