Abstract
Ultrafine powders are synthesized through cocrystallization of magnesium, aluminum, and silicon compounds. Spinel–cordierite two-phase composites are prepared based on these powders. The leaching of a chemically unstable phase in hydrofluoric acid solutions is studied. The optimum conditions are determined for treatment of two-phase materials with the aim of preparing ceramics based on the magnesium–aluminum spinel with an accessible porosity of higher than 50%.
