The Study of Dielectric and Microstructure Properties for Iraqi Kaolin Under the Effects of Binder and Calcinations.
Kaolin Duekhla
Poly acrylic acid (PAA)
calcinations
microstructure.
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.
