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.
