摘要：

BN was deposited on Al2O3 substrates from the BCl3-NH3-Ar reagent system. An impinging jet reactor configuration was used to obtain kinetic data in the temperature range of 800-degrees to 1000-degrees-C and in the pressure range of 4 to 20 kPa. The BN deposition could be described by a simple kinetic rate expression with an activation energy of about 39 kcal/mol and a first-order dependency on BCl3 concentration. The BN deposition rate increased with temperature, pressure, and BCl3 concentration. The microstructure of the BN coatings was not strongly influenced by the process parameters.
