Aluminum oxynitride by SHS under high pressure of nitrogen gas
Aluminum oxynitride (γ-AlON) powders were prepared from low-caloric Al–Al 2 O 3 mixtures by SHS under high pressure of nitrogen gas in the presence of heat-generating agent, Mg(ClO 4 ) 2 , as a booster. The preparation procedure was characterized and optimized with respect to Al/Al 2 O 3 ratio, amou...

ratio, amount of heatgenerating additive, and nitrogen gas pressure. The morphology of synthesized γ-AlON powders was found to depend on Al powder brand. Compared to γ-AlON powders obtained in chemical furnace, we managed to prepare less sintered arenaceous cakes that could be easily disintegrated into target γ-AlON powder. SHSproduced powders may find their application in production of optical ceramics. |
