Ultrafine particles of Pd-TiN system have been synthesized by "reactive plasma-metal" reaction, i.e., arc melting, vaporization and deposition of a binary Pd-Ti alloy in an atmosphere of a nitrogen-hydrogen mixed gas. X-ray diffraction and transmission electron microscope measurements have been carried out for the resulting particles. It is found that the typical morphology of the resulting ultrafine particles is a dumbbell-like particle consisting of single phases of Pd and TiN particles with the particle sizes of -20nm and -50nm, respectively. In addition, the ultrafine particles, synthesized from the parent alloys containing more than 60at%Ti, show solid solutions of Pd and TiN.
