Abstract
This study has investigated the effect of particle size of non-plastic components of
quartz and pegmatite on some technological properties of wall tile bodies. For this,
quartz-pegmatite mixtures were further milled up to 90 min. before adding into the
body composition unlike the standard body composition, where quartz and pegmatite
were used as-received. The physical and mechanical properties of the bodies were
investigated and compared with the standard values. Thermal expansion coefficient
and moisture expansion values were determined by a dilatometer. Phase analyses
were carried out by X-ray diffraction and microstructural characteristics were studied
using a scanning electron microscope. Changes in various technological properties
with reducing particle size of the non-plastic components were reported, particularly
the increased green and fired strength. It was discussed that using finer particle size
non-plastic raw materials of quartz and pegmatite would enable not only increased
industrial productivity but also increased producibility of thinner large format wall
tiles.
