Thermodynamic Analysis of a New Gas-Phase Method of Obtaining High-Purity Aluminum Nitride

Thermodynamic Analysis of a New Gas-Phase Method of Obtaining High-Purity Aluminum Nitride Ultradispersed high-purity aluminum nitride powder was obtained at the Physico-Technological Institute on a unique experimental-industrial unit by a gas-phase method.

Abstract

Ultradispersed high-purity aluminum nitride powder was obtained at the Physico-Technological Institute on a unique experimental-industrial unit by a gas-phase method. The powder was obtained through the formation of aluminum monofluoride. However, there has been very little thermodynamic analysis of the interactions of the materials in the reaction zone and in the charge. This study gives special attention to the selection of sintering additives and their effect on the removal of undesirable oxygen impurities during the synthesis of aluminum nitride. The mix that was obtained for sintering can be used for the energy-efficient single-stage production of aluminum-nitride finished products having excellent thermal conductivity.
