With the aim of searching clays that can be used to produce aluminosilicate refractory bricks, characterization studies were carried out on several clays of the region of Abidjan (Ivory Coast) with refractory potential. These studies concerning the chemical, geochemical, mineralogical and thermal characterization showed that clays of Alepe and Anguededou are very rich in kaolinite and have high alumina, and less proportion of melting alkalis and colouring oxides to be refractory clays. The use of geochemical AB diagram of La Roche adapted to clays indicates those Alepe and Anguededou would have a refractory character. These clays after the various characterization tests have also presented interesting chemical and physico-thermal aptitudes to be used in the elaboration of refractory bricks for the manufacture of ovens, blast furnaces, incinerators etc...
