摘要：
Nitrided high surface alumina powders were prepared by reaction of boehmite at 1370K under NH3 flow. According to experimental conditions, either AlON compound or AlON-Al2O3 composite could be obtained. In order to locate the nitrogen atoms in the composite, this surface was studied by IR spectrometry. The effect of deuteriation clearly showed that AlON groups surround Al2O3.
