The dependence of aluminum nitride yield on weight mass and air pressure at aluminum nanopowder combustion

Abstract

The authors have proved by the experiment the methods for increasing aluminum nitride yield in air combustion products of aluminum nanopowder: the increase of mass of aluminum nanopowder weight and air pressure rise. It was ascertained that increasing the mass of combusted aluminum nanopowder weight to 15 g or rising air pressure to 120 kPa it is possible to increase aluminum nitride yield approximately by 30 %. The earlier proposed mechanism of forming whiskers from gas phase was proved by the experiments
