Herstellung keramischer Pulver. II. Über die Bildung von Mg2TiO4, MgTiO3 und MgTi2O5 durch Hydrolyse von 2-Ethoxyethylaten

Preparation of Ceramic Powders. II. Mg₂TiO₄, MgTiO₃, and MgTi₂O₅ Formed by Hydrolysis of 2-Ethoxyethylates Solutions of 2-ethoxyethylates of magnesium and titanium in 2-ethoxyethanol submitted to hydrolysis, evaporation and heating of the residue up to 450°C allow to prepare Mg₂TiO₄, MgTiO₃, and MgTi₂O₅ in an amorphous state with smaller than 1% of volatile components. Highly dispersed powders showing an increased sintering activity are obtained as a result of recrystallization. Mg₂TiO₄ is formed as inverse spinel phase in a metastable state.
