【 摘 要 】

At present, no refractories are produced in Jordan, but large quantities are imported for usein the lining of furnaces and kilns in the metallurgical industries.The aim of this study is to initiate aprogram of research for production of silica-refractory bricks from local materials.The raw material,which has been used in this study was white sand. This sand contains less than 0.5% Fe₂O₃ and istherefore suitable for production of glass. The sand used for production of glass is also suitable forproduction of silica refractory bricks. The method for production of this bricks consists of mixing thewhite sand with 2.5 CaO (milklime) which acts as a binder and mineraliser in order to convert the freequartz to tridymite and crystobalite.
