Synthesis of Spinel from Caustic Magnesite and Alumina Dust

Abstract

The sintering of a mixture of a caustic dust and an alumina dust collected from electric filters taken in MgO/Al₂O₃ ratios of 0.1, 0.28, 0.5, and 0.75 at 1650°C is studied. Materials with superior physicomechanical properties are obtained: open porosity, 1.2 – 8.4%; density, more than 3.5 g/cm³, and compressive strength, 160 – 410 MPa. High-density pellets (free of additions) are prepared at a MgO/Al₂O₃ ratio of 0.75, with compressive strength as high as 160 MPa.
