Laser treatment of the ceramic material mainly composed on the basis of Y3Al5O12 (YAG) with secondary phases of Y2Ti2O7, Al2Y4O9, and Al2O3 is accompanied by fusion in the surface layer, the partial decoupling of Y3Al5O12, Y2Ti2O7 and Al2Y4O9, with formation of secondary phases and Al2O3 and Y3Al5O12 new phases as orthorhombic and hexagonal YAlO3 with modifications. As a result of laser treatment directed ceramic composite new type of ceramic material is formed. It consists of three layers with different thickness. The top layer is enriched with YAlO3, the middle layer (real body of molten trace ceramic) YAG mainly contains texturing and third layer is where laser-beam does not penetrate the content of these phases depends on irradiation regime and phase chemical composition of the ceramics. Y3Al5O12 crystallites in the second layer have textured. The crystallographic texturing (TC) depends on the irradiation regime and the phase relationship Y3Al5O12 / Al2O3.
