Development of Low Clay Whiteware Bodies

Abstract

In this project, triaxial body was prepared using clay quartz and feldspar. In the traditional triaxial body the percentage of clay is generally taken within 40- 60 weight percentage. In the present work the percentage of clay has been kept 25 weight percentage and quartz amount has been fixed to 50 weight percentage. Two different types of clays have been used for this present work. All samples are prepared by uniaxial pressing method, after pressing the samples are sintered at different temperatures at 13500c and 14500c with holding time of 2 hours. After sintering linear shrinkage was observed. To study the sintering behavior by dilatometry analysis has been carried out. After sintering the bulk density and apparent porosity was measured by Archimedian principle. Sintered body are grounded to powder and phase identification was analyzed by X-ray diffraction analysis. For mechanical property analysis , Brazilian Disk test has been carried out is measured
