Effects of Al2O3 phase composition on AlON powder synthesis via aluminothermic reduction and nitridation
Using micro-sized aluminum powder (11 wt.%) and nano-sized Al powder (89 wt.%) with five different phase compositions, AlON powders were synthesized at different temperatures in flowing-nitrogen atmosphere. Our results suggest that for starting materials with low γ-Al /total Al ratio (0 and 0.15), a...

| description | Using micro-sized aluminum powder (11 wt.%) and nano-sized Al
powder (89 wt.%) with five different phase compositions, AlON powders were synthesized at different temperatures in flowing-nitrogen atmosphere. Our results suggest that for starting materials with low γ-Al
/total Al
ratio
(0 and 0.15), a calcination temperature of 1 750 °C is required to obtain single-phase AlON. This temperature is about 50 °C higher than for other batches starting with larger
values (0.5, 0.85, and 1.0). The AlON powders fabricated from reactants with a high
value in this work show narrower particle size distribution and better particle homogeneity than those prepared from batches with lower
values. |
