文摘Ultrafine particles of Al_(2)O_(3),MoO_(3),TiO_(2)and SiO_(2)were prepared by irradiate high power laser beams on material surface in O_(2)atmosphere as well as TiN in N_(2) atmosphere.X-ray diffractometer analysis identified that all oxides and nitrides powder obtained are crystalline except SiO_(2) particles which have amorphous struc-ture.
