Temperature effects of Si milling in NH3

Journal Article


Abstract


  • ��-Si3N4 has been formed by ball milling of pure Si in NH3 and subsequently annealed in Ar. Milling was carried out at room temperature and 100 ��C and the N content varies with milling temperature. For the case of milling at 100 ��C, the complete formation of an amorphous SixNy phase was obtained after 48h milling, compared with 168h at room temperature. Both as-milled and annealed samples were investigated by X-ray diffraction, composition analysis, DTA and TGA. The results show that the crystallization temperature of a-Si3N4 decreases or increases in a complex way with increased milling time depending on milling temperature. The results are discussed in terms of competing adsorption / desorption and reaction processes during milling.
