Abstract
Powder preparation by using spark discharge between zirconium rotating disk electrode and wire electrode in liquid nitrogen and in deionized water were studied.Zirconium and zirconium nitride (ZrN) powders containing spherical and irregular shape particles were obtained in the case of liquid nitrogen. By applying deionized water instead of liquid nitrogen, spherical particles containing zirconium and zirconium oxide (ZrO2, monoclinic) powder were formed.Spherical particles were formed by drop splashing from melting zone on electrodes. Irregular shape particles were formed by spalling from nitrized zone on electrodes.
