More Information
Summary:A batch composition comprises 68-97 wt.% molten magnesite, sintered magnesite or their mixtures containing more than 93 wt.% and a having a grain size of less than 8 mm; 3-20 wt.% calcium oxide with a grain fraction of less than 1 mm; and 0-25 wt.% of at least one further refractory component having a grain size of less than 3 mm. Preferred Features: The further refractory component is made from SrO, TiO 2, ZrO 2, SiO 2 CaO-MgO molten material, SrO-CaO molten material, SrO-ZrO 2 molten material and/or non-oxidic strontium compounds.
