Magnesium aluminate spinel (MgAl₂O₄) is an important refractory material of magnesia origin. It is formed by the reaction of magnesium and aluminum oxides. In this study, TiO₂ was added to magnesite waste and alumina (Al₂O₃) powders in different proportions and the mixtures were sintered at different temperatures after shaping. The aim of this study was to produce spinel economically by recycling waste materials. Therefore, titanium dioxide (TiO₂) added magnesium aluminate spinel was produced and the products obtained were characterized by XRD and SEM-EDS analyses. In addition, bulk density, apparent porosity and microhardness values were measured and the effects of TiO₂ additive on magnesium aluminate properties were examined. The better values were determined in samples doped 4 wt.% TiO₂ at the sintering temperature of 1400°C.
