Abstract :Experimental compositions were prepared by the additions of ulexite concentrator waste to a standard wall tile body sintered at different temperatures. Tests of linear firing shrinkage, water absorption, and fired bending strength (eğilme mukavemeti) were done. XRD analyses were conducted to determine major crystalline phases in wall tile bodies. SEM-EDX analyses were performed to study the microstructural evolution of the standard and experimental wall tile bodies . Colorimetric analyses were also made . T he wall tile body containing 5 weight percent ulexite concentrator waste fired at 925 o C for 6 minutes was determined to be the optimal composition with 0.60 % of linear firing shrinkage, 17.66 % of water absorption, and 208.60 of kg/cm 2 fired bending strength (eğilme mukavemeti) . Sintering temperature was reduced from 1182 o C of industrial practice down to 925 o C. Utilization of ulexite concentrator waste in tile bodies will help reduce energy costs in favour of the environment and economy.
