Improvement of the Mechanical and Dielectrical Properties of Kaolin Clay

CaO . . HCl XRF . HCl Fe2O3 . This paper examines the influence of certain additives such as Sawdust ,CaO and quartz have been added with different proportions on Hardness and compression strength of the local kaolin .In general ,the additives used have increased the hardness and compression strength . The quantitative and qualitative analysis of the local kaolin before and after treatment with HCl acid solution was achieved using XRF technique . It has been found that the treatment of kaolin with HCl acid solution reduces the concentrations of Fe2O3 and alkali metals ,thus improving the dielectrical properties .
