The reactive‐electrode submerged‐arc (RESA) method utilizes metal electrodes submerged in a dielectric fluid to produce fine ceramic powders. An arc is struck and causes localized vaporization of the electrode and reaction of the metal with the fluid vapor. This paper reports the extension of this process from oxide to non‐oxide powders. Fine particles of TiC and SiC have been synthesized and characterized by SEM, TEM, and XRD.
