Magnesia refractory products magnesia products are alkaline (basic refractory). High melting point refractory magnesia, so the use of high temperature refractory material price, can be used in an oxidizing atmosphere to 2000 ℃, in a reducing atmosphere can be used to more than 1700 ℃. Because anti-alkaline slag erosion resistance, suitable for smelting many metals, precious metals, heavy metals and rare metals. Magnesia ceramics production methods: Alcohol injection molding mud burn, burn grout injection molding, isostatic molding, extrusion molding mud and machine molding method. Refractories (Refractory material) by forming process can be divided into seven categories: (1) natural rock molding process; (2) pressing refractories (Refractory material); (3) casted refractories (Refractory material); (4) plastic molding refractories (Refractory material); (5) Ramming (including mechanical and manual ramming ramming) forming refractories (Refractory material); (6) injection molding refractories (Refractory material); (7) Extrusion refractories (Refractory material).
