The structural properties of a natural clay sample (۵۱% kaolinite) were tweaked to suit specific applications. H۲SO۴ and NaOH (۱.۰ M) treatment caused structural alterations and a significant release of Al ions compared to Si ions. Chemical treatment caused structural alterations, according to XRD analysis. FTIR analysis also indicated higher density of polar surface groups upon treatment which affected the corresponding dielectric behaviors. Dielectric measurements shown the suitable application of the materials either as dielectrical insulator and this dependent on the applied frequency. Acid treated kaolinite was reported to be a promising dielectric at ۱۰ and ۱۰۰۰ Hz. With appropriate mass attenuation coefficients (μ/ρ) ۱۲.۰۹۸-۱۲.۱۸۲ cm۲/g and a high half value layer of ۱۰ cm at ۱۰ keV, kaolinite and other treated forms were adequate shielding materials.
