Autohydration of Nanosized Cubic Zirconium Tungstate
Nanoparticulate zirconium tungstate prepared through hydrothermal methods was found to autohydrate under ambient conditions. This results in positive thermal expansion, limiting its usefulness for controlled thermal expansion composites. TEM and BET studies provided strong evidence that the cause of autohydration is a result of structural defects present in the nanoparticles, while kinetics are...
متن کاملDynamic nuclear polarisation NMR of nanosized zirconium phosphate polymer fillers.
Surface functionalisation with organic modifiers of multi-layered zirconium phosphate (ZrP) nanoparticles used as polymer fillers can be directly probed by dynamic nuclear polarisation NMR, which provides unambiguous evidence of the presence of P-O-C chemical bonds at the surface of the ZrP layers, thereby confirming successful functionalisation.
متن کاملOptical and Dielectric studies in zirconium(IV) tungstate nanoparticles prepared by chemical coprecipitation method
Nanoparticles of zirconium(IV) tungstate are prepared by chemical co-precipitation method. Thecharacterizations have been carried out by TG/DTA, DSC, AFM, XRD, FTIR and UV-Vis spectrum. PLspectrum shows two emission bands at 350 nm and at 477 nm. The effects of frequency on the dielectricbehavior and ac electrical conductivity have been studied. The dielectric constant is found to be 119.43 at1...
متن کاملSynthesis, Characterization and Sorption Behavior of Some Radionuclides on Zirconium Tungstate Ion Exchanger
Zirconium tungstate as an inorganic ion exchange material has been synthesized at different conditions. The materials were characterized by means infrared spectroscopy, thermo gravimetric analysis, and X-ray diffraction techniques. The stability of the ion exchangers was investigated in acidic and alkaline media. Ion exchange properties of synthesized materials were studied by measuring the dis...
