Abstract:

The oxidation characteristics of hot-pressed aluminum nitride were investigated. Three materials were studied in the temperature range 1100 to 1400 C in 15, 150, and 400 torr oxygen environments. The oxidation process was evaluated using thermogravimetric measurements, X-ray diffraction, optical and scanning electron microscopy and electron microprobe results. Modified author abstract
