An optimum route to synthesis the W-based composite powders with homogeneous dispersion of oxide nanoparticles was investigated. The La₂O₃ dispersed W powder was synthesized by ultrasonic spray pyrolysis using ammonium metatungstate hydrate and lanthanum nitrate. The dispersion of Y₂O₃ nanoparticles in W-La₂O₃ powder was carried out by a polymer addition solution method using yttrium nitrate. XPS and Tem analyses for the composite powder showed that the nano-sized La₂O₃ and Y₂O₃ particles were well distributed in W powder. This study suggests that the combination processing of ultrasonic spray pyrolysis and polymeric additive solution is a promising way to synthesis W-based composite powders.
