SYNTHESIS OF NANO SIZED YTTRIA STABILIZED ZIRCONIA PARTICLES BY A NEW EMULSION TECHNIQUE
A new emulsion technique is successfully employed to prepare 8mol% yttria stabilized zirconia powder, in which metal alkoxide of zirconium is used as a precipitating agent for yttrium hydroxide. Nano-crystalline cubic phase YSZ particles are obtained after calcination of dry precipitate. The powders are characterized by X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), energy dispersive X-ray spectroscopy (EDX), specific surface area analyzer (BET) and particle size analyzer (PSA). The diffraction pattern results reveal the sole presence of cubic zirconia. The particle size is determined by FESEM, supported by BET specific surface area analysis. The particle size analyzer (PSA) result revels that the powder has narrow size distribution. All the analyses give consistent results and show the method is effective to synthesize nanocrystalline powders. The sintering property and microstructure evolution of ceramics are also investigated.
