Publikováno v: Journal of Asian Ceramic Societies, Vol 5, Iss 4, Pp 422-426 (2017)

Four mixtures of kaolinite clay and feldspar (Western-Cameroon) were prepared and sintered at 1200 °C for 2 h at the heating rate of 5 °C/min, 10 °C/min, 15 °C/min and 20 °C/min. The main new crystalline phase was mullite associated with quartz,

Autor: L. Zerbo, M. Seynou, B. Sorgho, G. Lecomte-Nana, M. Gomina, P. Blanchart

Publikováno v: Cerâmica, Vol 65, Iss 374, Pp 240-245

Abstract The mechanical properties of clay-talc ceramics containing 0 to 10 wt% of talc fired at 1100 °C were obtained by flexural measurements. With the average value of flexural strength of 23.1 MPa, the sample with 5 wt% of talc (G5) was the stro
