| Abstract: | Nano particles of cerium tungsto iodate, a
tetravalent metal acid salt, have been prepared by chemical co-precipitation
method. The particle size of the sample has been calculated from its X-ray
diffraction pattern and the average grain size is found to be 25 nm. The size
is further characterized by SEM, TEM and FTIR analyses. Its dielectric
behaviour at various temperatures (50°-110°C) and
frequencies is also investigated. The dielectric constant values increase with
the decrease in frequency and the increase in temperature. Moreover, the sample
in its protonated form is subjected to ion exchange capacity studies. The data
reveals that the sample works as a good ion exchanger.
