Synthesis of Al2O3 + хFe–based thermocrystals

Abstract

Al₂O₃ + хFe thermocrystals with specific sizes of the metal phase (65–100 nm) and no spinel phase at their interfaces are obtained via mechanical activation of a mixture of aluminum oxide and iron carbide preliminarily transformed into the nanocrystalline state, with subsequent sintering below the recrystallization point.
