Abstract

The effect of Cr-doped soda-lime scrap glass in normal porcelain composition substituting feldspar partially on their physico-mechanical properties such as % linear shrinkage, % apparent porosity, bulk density and flexural strength were studied in the temeprature range of 1100C to 1250C and the data was compared with normal porcelain composition. It was observed that incorporation of Cr-doped soda-lime scrap glass in place of feldspar enhances the vitrification and develop higher flexural strength. The phase and microstructural evolution were analysed by XRD and FESEM studies. The porcelain with Cr-doped soda-lime silica glass shows formation of needle shaped mullite crystals. No significant change in crystal morphology was noted when compared with normal porcelain sdudied earlier by the same authors. However presence of large no of smaller sized mullite crystals are seen in the presently developed scrap glass incorporated porcelain composition.
