Abstract
This study focuses on the effect of firing temperature on the physical properties of Same clay and Pugu kaolin for potential application in ceramic tiles. X-Ray diffractometer (XRD) is used to analyze the phases formed after firing. XRD result shows that quartz, sillimanite and cristobalite appears at temperature beyond 1200oC while mullite phase develops in Pugu kaolin. Pugu kaolin shows low porosity (1.3%) at 1400oC compared to that of Same clay (12.7%). Water absorption at 1200oC is 7.8 % for Pugu kaolin and sharply reduced to 0.47% at a temperature between 1300oC to 1400oC suggesting complete sintering to have taken place at this temperature.
