The composites are prepared by sintering Al2O3/NiAl powder mixtures at 1600°C in a mixture of nitrogen and carbon monoxide. The presence of NiAl particles raises the green density of Al2O3/NiAl powder compacts. During sintering, NiAl reacts with nitrogen to form AlN and Ni inclusions. A volume expansion accompanies the reaction. Because of the high green density and the reaction, the volume shrinkage of the Al2O3-AlN-Ni composite decreases with the increase of added NiAl content.[SDGs]SDG6Alumina; Carbon monoxide; Densification; Density (specific gravity); Firing (of materials); Nickel; Nitrides; Nitrogen; Powders; Residual stresses; Sintering; X ray powder diffraction; Ceramic powder; Green density; Volume expansion; Volume shrinkage; Ceramic matrix compositesjournal article10.1111/j.1151-2916.1997.tb03136.x2-s2.0-0031234794
