Refractory Materials are usually non-metallic materials having those chemical and physical properties that make them applicable for structures, or as components of systems, that are exposed to environments above 1,000 °F (811 K; 538 °C)。

They are produced using natural magnesite as raw material in electric furnaces. The products have high quality. The growth of grains and bulk density of grains are more even than dead burned magnesia. They are the best raw material in reborn products and MgO-C products.
