Raw materials for your needs

By fusing in an electric arc furnace, Fused Magnesia can be produced, which along with sintered magnesia is used for refractory bricks (e.g. to line steel furnaces or cement rotary kilns) and for electrical insulation in furnaces. Magnesia has a melting point of approx. 2800°C. Here too there are single-stage and two-stage processes in which either magnesium carbonate is fused directly or via the interim stage of caustic calcined magnesia. Fused Magnesia can also be produced in a flotation where rejects or lower category raw stone is milled and impurities are washed out. Material is briquetted, caustic calcined then fused, screened and crushed.
