High purity ALUMINA fire-resistant SDA High ALUMINA fire-resistant DA High purity ALUMINA and high ALUMINA fire-resistant substances provide high resistance to acid, alkali ‘SLAG” and fire resistance over SK-38, as they are neutralized. Therefore, these substances are widely used as tools of high temperature continuous furnace, interior structure of electric furnace, and baking furnace for electron parts. The products have a variety of ranges that provide high abrasion and spalling resistance. ALUMINA · MULITE fire resistant substance  DN Provides high heat and strength as well as spalling resistance. Major ingredients are molten MULITE.  SDA-4 Provides high heat and strength as well as abrasion resistance. Major ingredients are ALUMINA and MULITE.  DAD A neutral fire resistant substance that provides stable heat and chemical resistance. Major ingredients are ALUMINA and MULITE. Advanced fire-resistant heat insulator, BA.BB A high temperature resistant adiabatic substance that is made majorly with electrofused ALUMINA tool. It can be used in downsizing of high temperature furnace as well as vigorrizing as it provides high insulating effect and stable loaded softening point. >DIALITE - Silicon carbide SDC. DC - Silicon carbide refractory DC-N - DC-M, comparable to Silicon carbide · MULITE
