 · Dolomite was traditionally used as fettling material for the hearth of furnaces (Bessemer converter) . Hydration of dolomite refractory is a major problem due to the presence of CaO phase. To minimize this problem, at earlier times stabilized doloma was produced with the reaction of dolomite with silica or iron oxide materials [4] .
