Abstract

The present study is in line with sustainability and environmental issues
regarding the utilization of local materials and wastes for developing silicate ceramics in
RCA (Central African Republic). Two clay deposits were selected for this purpose and
noted NZ1 and KO. Their chemical and mineralogical analyses revealed the presence of
major clay mineral phases as kaolinite and illite; while quartz, and iron oxide/hydroxide
phases were detected as secondary crystalline phases. The use of Winkler and chemical
composition diagrams, according to the results of chemical analysis and granulometry of
these clay materials, indicated their suitability as starting materials for the manufacture of
earthenware ceramics.
