Abstract: Magnesium nitride powder of nanometric size was prepared by reaction of magne sium in highly reactive form (Mg*) with nitrogen gas under mild conditions in high yields.This Mg* was obtained by the thermal decomposit on of magnesium anthracene.3THFat 200℃ under vacuum.The average particle size of Mg3N2 obtained is around 20-3Onm as shown by the transmission electron microscopy.At 450 ℃ at normal pressure of N, atom sphere, the yield of Mg3N2 by the nitridation of Mg doped with NiCl2 is 93% in 20 h.

Key words: Magnesium nitride of nanometric size, Active form of magnesium, Magnesium anthracene
