Characterization for Ceramic Applications of Clay Materials from Lembo Deposit, Mount Bana (Cameroon)
Résumé
The mineralogical composition of 10 different samples, coming from Lembo (Western Cameroon) has been discussed and estimated in order to seek their ceramic applications. The following analyses have been used: chemical analysis, X-ray diffraction, TGA, DTA and infrared spectroscopy. The results reveal that all the samples are suitable for ceramic applications. In particular, the compositions of samples LB3 and LB9 are very close to those of the mixtures used for the manufacture of ceramic products presenting sintering ability and mechanical properties. Sample LB3 (illite content, 34+/-4 %) could be used for the manufacture of low firing temperature products. Iron-poor sample LB9 (kaolinite, quartz and microcline in proportions approx. 1/3, 1/3 and 1/3) could be used for high firing temperature products. However, the composition variability of the studied samples could generate complication for industrial exploitation of the deposit.
