Preparation and characterization of monodisperse zirconia spherical nanometer powder via lamellar liquid crystal template method
Cubic phase spherical zirconia nano-powder was prepared by a direct template route in the lamellar liquid crystal formed by polyoxyethylene tert-octylphenyl ether (Triton X-100)/sodium dodecyl sulfate (SDS)/H2O. The precursor powder and zirconia powder were characterized by XRD, FT-IR, TG/DSC, TEM, and SEM methods. Results show that the stability of the lamellar liquid crystal is controlled by NH3 center dot H2O concentration. The size of nanoparticles is greatly affected by NH3 center dot H2O and ZrOCl2 center dot 8H(2)O concentrations. The zirconia nanoparticles show narrow particle size distribution of 10-30 nm.
