Abstract

Porous Anodic Alumina (PAA) was prepared by two-step anodization on both sidesof an aluminium foil. The anodization carried out at anodizing temperature 17oC usingoxalic acid as an anodizing electrolyte. The (PAA) template was characterized withoptical microscope and SEM. The optical microscope image showed two (PAA) layersafter the dissolution of the residual aluminium. The average pore diameter was found tobe (75) nm. The average interpore distance of (PAA) prepared was found to be (99) nm.The thickness of (PAA) was found to be (59.5) μm.

Abstract

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.

ان المعاملة تحت تأثيرعمليات الكلسنة (التحميص) والمادة الرابطة بولي أكرلك أسد ((1wt% على حبيبات الكاؤؤلينيت تمت دراستها من خلال الفحوصات التشخيصية للاشعة السينية والمجهرية والقياسات العزلية وتبين ان العينة المكلسنة عند 850م˚لمدة 3ساعات والملبدة الى 1350 م˚لمدة ساعتين امتازت بنقصان في التعريض عند منتصف الشدة (FWHM) وزيادة في ثابت العزل.
