Abstract
The structural properties of a natural clay sample (51% kaolinite) were tailored to suit specific applications. H2SO4 and NaOH (1.0 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 behavior. Dielectric measurements showed their suitability in the frequency dependent dialectical insulator applications. Acid treated kaolinite was a promising dielectric at 10 and 1000 Hz. With appropriate mass attenuation coefficients (μ/ρ) of 12.098-12.182 cm2/g and a high half value layer of 10 cm at 10 keV, kaolinite and other treated forms were adequate to act shielding material.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
