مرکز منطقه ای اطلاع رساني علوم و فناوري - The Research of the Usability of Unenriched Talc in Wall Tile Bodies

Abstract :

In this study, the talc sample obtained from Domaniç (Kütahya) region of Turkey together with the raw materials used for making fast and single-fired wall tile are studied by the use of various prescriptions concerning the effects on the technical features of several properties. The samples prepared under laboratory conditions are shaped with pressing method and fired at 1130 °C. The chemical compositions, granule dimensions and moisture content of talc and spray dried granules are determined. Thermo gravimetric and differential thermal analysis of the powder of these materials which were prepared based on the prescriptions are done. Water absorption, fired strength, fired shrinkage, true density, X-Ray diffraction analysis and scanning electron microscope analysis of sintered samples are done. To sum up, it was observed that the fired strength of the wall tile bodies with 15 % talc addition was increased by 1.07 times whereas water absorption value was decreased by 16.22 %. In this respect, it is apparent that these values are well-matched and in accordance with TS EN 14411:2008.
