摘要：

Initiation of a reaction between lithium nitride and anhydrous metal halides induces a spontaneous exothermic self-propagating reaction. The products were washed with methanol and analysed as crystalline metal nitrides (TiN, ZrN, HfN) by X-ray powder diffraction, SEM-EDXA, FT-IR, microanalysis, XPS and magnetic moment measurements. The crystallite size and composition can be controlled in the reaction by the addition of an inert heat sink. Differential Scanning Calorimetry shows exotherms at 200-500 degrees C, whilst thermocouple measurements show a reaction temperature in excess of 1000 degrees C. (C) 1998 Elsevier Science S.A.
