摘要

The particle size and shape effects of starting raw powders on the synthesis of aluminum nitride by combustion reaction technique were investigated with four sizes of A1N powder as diluent and two shapes of Al powder as reactant. It was found that the structure of beds of starting particles significantly affected the pore channels for nitrogen gas accessibility into a mixture compact and the passages for combustion wave propagation through particles, resulting in changes of A1N product morphology and purity. Through control of the starting particle size and shape, high-purity (over 98 percent) A1N products several tens of microns in size were synthesized.
