Effect of zirconia nanoparticles on physical properties and compressibility of synthesized zirconia powders by co-precipitation method
Abstract:   (11660 Views)
In the current investigation, zirconia nanopowders with zirconia nanoparticles content of 0 and 10 %wt was synthesized via chemical co-precipitation method. Zirconium oxycloride and cerium nitrate salts were used as the precursors .Calcined nanopowder of zirconia was added through synthesis processing of the two types of 0 and 10%wt zirconia nanopowders. Appropriate calcined temperature of dried powders and physical properties of the resultant powders were studied by Differential Thermal Analysis (DTA), X-ray diffraction (XRD), specific surface area measurement by BET method, Dynamic Light Scattering (DLS) and Scanning Electron Microscopy (SEM). Added zirconia nanoparticles act as heterogeneous sites, so crystallite size was enlarged. The compaction behavior of the calcined powders revealed that however less value in the slope of the raw density curve on the pressure logarithm (α=A3/A2), caused in better compressibility of the specimen .Based on the results, raw density increasing in the sample without zirconia particle (%0 wt) was higher than the sample with zirconia particle content of 10% wt.
Keywords: zirconia powder, crystallite, primary particle, agglomerate, compressibility curve.
