Laser focusing can achieve high temperature, so ceramics with high melting point and high strength can be fabricated by laser synthesizing without sintering flux. In this paper, Al2O3, Al2O3-5%mol Cr2O3 and Al2O3-20% wt ZrO2 powders have been sintered to fabricate oxide ceramics with a CO2 laser of 600-2000w. The product of Al2(WO4)3 is found as a new compound which is missed in two dimensional equilibrium phase diagrams. The microstructure of this ceramic is analyzed by use of X-ray diffraction, metalloscope and scanning electronic microscope. The hardness is measured by durometer. It is shown the hardness is higher than that produced with conventional sintering method in furnace.
