Abstract
The particle size and morphology of AlN product powders from carbothermal synthesis have been studied by scanning electron microscopy, surface-area measurement and microarea elemental analysis. AlN powders with widely variable grain size and morphology could be produced by varying the pressure, gas-flow rate and alumina type. Discrete AlN particles (∼0.5-3 μm) were obtained by using fine γ-Al 2 O 3 as starting material at 1600 o C over the pressure and gas-flow rate ranges 0.1-5 MPa and 1-10 l min -1 . When coarse α-Al 2 O 3 was used as raw material, large aggregates of AlN particles normally formed, unless the reaction was run at high nitrogen pressure (5 MPa) and low gas-flow rate (1 l min -1 )
