A novel method for the preparation of TiN-Al2O3 nanocomposites was developed. TiN-Al2O3,, nanocomposite powders were prepared by the direct nitridation of TiO2-Al2O3 nanocomposite powders that were derived from the simultaneous hydrolysis of tetra-butyl titanate and precipitation of aluminum nitrate. Dense sintered bodies of these TiN-Al2O3 nanocomposite powders were obtained by hot pressing at 1450degrees-1650degreesC and 30 MPa for 60 min. The resistivity of nanocomposite reaches a minimum (1.5 x 10(-3) Ohm(.)cm) at 25 vol% TiN additions. The percolation concentration of nanocomposite is similar to10 vol% TiN.
