Abstract

A dense electroinsulating ceramic was prepared at lower temperature (1400–1450 °C) compared to the solid phase synthesis. The synthesis of the spinel was carried out at 1000 °C reaching over 97% spinel by applying the sol-gel method and the inclusion of one of the components as a soluble salt. Combinations of additives like B2O3 and TiO2 were included as alcoholates during the process of hydrolysis. These additives caused an intensification in the course of the process of spinel-formation.
