Abstract
Fly ash in the range of 10-60% has been used to replace calcined alumina in a wear resistant ceramic composition. The compositions containing has been sintered in the temperature range of 1500-1600ºC. The physical properties such as apparent porosity, bulk density, compressive strength, macrohardness and abrasion resistance was studied as a function of fly ash content and sintering temperature. It was observed that incorporation of 30-40 % fly ash gives the best results. XRD phase analysis shows the presence of predominantly mullite phase which formed due to reaction sintering of alumino-silicate materials. The physical and wear resistant properties were found to be associated with compact microstructure.
