A phenomenon of transformation of sapphire surface layer with the formation of a new cubic phase of spinel (AIAI₂О₄) structure as a result of high temperature reducing annealing has been revealed. The result of microscopic investigations and X-ray diffraction analysis of the new phase layer on sapph...
