Abstract

Chemical and microstructural changes occurring when AIN and TiO2 are put in contact at 1400 to 1600‡ C in nitrogen have been studied. Experiments were carried out with single-crystal TiO2 embedded in AIN powder compacts, and with AIN + TiO2 powder mixtures of varying relative proportions. A displacement type of reaction is shown to take place yielding Al2O3 + TiN, with an intermediate step when a reduced titanium pseudobrookite (Al, Ti)2TiO5 phase is generated and subsequently tends to disappear. For appropriate AIN/TiO2 initial ratios, a fine homogeneous two-phase composite microstructure may be obtained between Al2O3 and TiN reaction products.
