摘要: Cubic phase spherical zirconia nano-powderwas 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 · H2O concentration. The size of nanoparticles is greatly affected by NH3·H2Oand ZrOCl2 · 8H2O concentrations. The zirconia nanoparticles shownarrow particle size distribution of 10-30 nm.
