Abstract

The X-ray diffraction and laser Raman techniques have been employed to analyse the situation of the tungsten impurity in α-Al2O3 grains in the samples of the Al2O3WO3system synthesized by a high power CO2 laser. The expermental results reveal that tungsten ions exist in the α -Al2O3lattice through replacing Al+3.
