Abstract
Abstract: The scope of the research was to assess and evaluate the phase composition of different kinds of kaolinitic sand in Sinai, Egypt, and its possible applications in ceramic industries. For this purpose, four samples of kaolinitic sand were mechanically dry and wet sieved, and the percentages passing through sieves sizes of different sizes for each sample were calculated. Chemical and mineral investigations, as well determining their stoichiometric phase composition, were carried out on the raw samples as well as the ones fired at 1200 and 1400°C, respectively. It was concluded that these samples could be used as aluminium silicate concretes and bricks for lining of different types of furnaces after firing at temperatures > 1550°C.
