• Refractory Manufacturing

    refractories include kaolin, bentonite, ball clay, and common clay. Nonclay refractories are produced from a composition of alumina (< percent), mullite, chromite, magnesite, silica, silicon carbide, zircon, and other nonclays. Refractories are produced in two basic forms, formed objects, and unformed granulated or plastic compositions.
