The weight increase can be attributed to the fact that the Al particles were partially changed into A1N via a
nitridation reaction.

nitridation of silicon powders diluted with [alpha]-[Si.sub.3][N.sub.4] at normal pressure," International Journal of Minerals, Metallurgy, and Materials, vol.
The
nitridation steels are 30Cr3MoA, 32Cr3MoVA, 38CrMoAlA, and so on.
Molecular nitrogen is rather inert gas, but atomic nitrogen is quite reactive, which is made use of in plasma deposition of nitride films [12] or plasma
nitridation [13].
Passivation of interface traps by
nitridation of the oxide at high temperatures is currently the standard method for achieving acceptable channel mobility.
Accurate change in the ratio of Si to Al in SiO2-Al2O3-C nanocomposite is among the unique characteristics of Al-SBA-15 nanocomposite to synthesize SiAlON through carbothermal reduction and
nitridation process.
At present, commercial AlN powder is produced via carbothermal reduction of [Al.sub.2][O.sub.3] or direct
nitridation of aluminium metal powder [13].
