Synthesis of Aluminum Oxynitride in Air

The CCP of mixtures of pAl with nano-y-Al203 (S3p 252m g ) burned in air contained significant amount of aluminum oxynitride, which underlined the diversity of the products obtained by CS in air depending on the particle size of the 

In addition, the insulation layer consisting of aluminum oxide prevents Al melting in the combustion wave. Thus, the reaction with N2 (5.7) is possible for the mixture of pAl with nano-Y-Al203  

The burning of the mixtures of pAl with nano-Y-Al203 in air occurs in one or two stages, that is, similar to the burning of pAl powder without additives. The mechanism of AlN (AI3O3N) synthesis at the mixtures combustion is obviously similar to the combustion of nAl similar combustion scenario and the composition of CCP. 

the new class of chemical reactions with nonequUibrium products (nitrides and oxynitrides) formation at the high-exothermal metals of III-IV groups combustion in air was experimentally confirmed.
