Synthesis and investigation of magnesium chromium spinel

Magnesium chromium spinel nanopowders have been synthesized through cocrystallization. The formation and structural perfection of the MgCr2O4 crystalline phase have been investigated in the temperature range 500-1400A degrees C. The average size of crystals of the MgCr2O4 phase has been determined at different temperatures. The influence of the temperature, porosity, and reducing medium on the electrical conductivity of the MgCr2O4 phase has been studied.
