Abstract: Aluminium nitride(AIN) containing higher nitrogen(33.5wt%) was prepared by self-propagatinghigh-temperature (combustion) synthesis (SHS) of aluminium powder in pressurized nitrogen atmosphere, and the effects of diluent content, additive content, nitrogen pressure, relative density ofreactants, thickness of reactants on nitrogen content of AIN were studied. After-burn phenomena,AIN whiskers and AIN stick crystal were also observed.

Key words: SHS, AIN, high pressurized nitrogen, AIN whiskers, AIN stick crystal
