SOLID-STATE SYNTHESIS AND PHYSICO-CHEMICAL CHARACTERIZATION OF MODIFIED SMECTITES USING NATURAL CLAYS FROM BURKINA FASO
Issaka Garikoé, Brahima Sorgho, Boubié Guel and Ingmar PerssonSolid-state intercalation was applied to prepare organo-smectites using cationic surfactants and natural clays containing smectite at various surfactant/smectite ratios. The surfactants enter the interlayers of smectites causing a swelling of the clays. The used clays were collected in...

Formulation of clay refractory bricks: influence of the nature of chamotte and the alumina content in the clay
Moustapha Sawadogo, Mohamed Seynou, Lamine Zerbo, Brahima Sorgho, Gisèle Laure Lecomte-Nana, Philippe Blanchart, Raguilnaba OuédraogoAbstract: Refractory materials from kaolinitic clays and clay chamotte or quartz were studied to increase the refractoriness
under load at temperature above 1300°C. Two different clays mined in Burkina Faso were used and chamotte grains were
obtained by preliminary firing a local clay....
