The Study of Dielectric and Microstructure Properties for Iraqi Kaolin Under the Effects of Binder and Calcinations.


The calcination treatments and a binder of poly acrylic acid PAA (1wt%) effects on kaolinite particles were investigated through dielectric properties at 1MHz ,quantitative analysis of X-ray diffraction and microstructure. The calcinated samples at 850°C/3hr and fired at 1350°C/2hr were revealed decrease in broadening (Full Width at half maximum) FWHM and increase of dielectric constant.
