GUTIERREZ-CAMPOS, D et al. Polvos nanométricos de zirconia, por síntesis hidrotérmica microonda. Rev. LatinAm. Metal. Mater. [online]. 2010, vol.30, n.2, pp.181-189. ISSN 0255-6952.

Stable colloidal suspensions of zirconia were used to synthesize nanometric powders through a micro-wave hydrothermal route. The effect of this novel method upon structural features and capability to sintering was evaluated. In addition, doping of zirconia with itria and ceria was performed and treatment variables were studied. Results showed nanometric powders in the order of 100nm. Also, XRD analysis indicated the presence of crystalline phases as those reported by the literature. It is concluded that this novel technique is promising for future developments and processing of high-purity nanometric ceramic powders.

Keywords : Zirconia; nanometrics powders; micro-wave hydrothermic synthesis.
