Abstract

A combustion synthesis method was developed for synthesis of AlN powder. Al powder and small amounts of urea were thoroughly mixed and placed in aluminum containers. A layer of AlN powder was placed on the top of the reactant powdersand in between the reactant powders and the container walls. The combustion reaction was ignited by heating the top surface of the powder stack and the aluminum container was converted completely to AlN during combustion reaction. High product yields (∼99.5%) were obtained under N2 pressures of 0.3–0.5 MPa. The product as synthesized is porous and loose and can be easily ground. A quenching technique was developed and formation of the various types of product morphology was investigated. Effects of several process parameters on the product yield were also studied. These results were reported and discussed.
