Thermochemical transformations of ilmenite – leucoxene concentrate

Abstract

Porous silicate-ferropseudobrookite composite material manifesting the properties of a ceramic n-type semiconductor has been synthesized by vacuum-heat treatment of ilmenite -leucoxene concentrate modified by additions of magnesium oxide. The microstructure and the chemical and phase compositions are described, and the mechanical and electrophysical characteristics of the material obtained are investigated.
