· These spinels have either magnesia rich or stoichiometric composition. In the late 1980 s spinel containing alumina refractories were also developed especially castables for steel ladle lining in Japan. However magnesia rich spinels have shown disadvantages for such applications because they are designed to contain traces of free magnesia.
