ZrN powder was prepared from ZrCl_4 ml/min) at the temperatures from 200℃ to 1050℃. Particularly, the influences of reducing agents, Al, Mg and Zn powder were examined.

The apparent activation energy of the reaction was 28.7kcallmol (850℃-1050℃). The fine powder (0.1-0.3μm) of onephase ZrN was obtained at l050℃ after 1 h.
