In this study the use of a treated palm oil fuel ash (POFA) as a substitute material in producing an improved porcelain ceramic has been presented. The POFA was grounded in a ball mill until the median particle size was reduced to about 50 μm. The POFA was heated at a temperature of 600 oC for 1.5 h in an electric furnace. It was used to substitute quartz in porcelain body from 0 wt% to 25 wt%. The mixed powder was pressed into pellets at pressure of 31 MPa, 61 MPa, 91 MPa and 121 MPa. All the pellets were sintered at a temperature of 1100 oC for 2 h soaking time. It was found out among other things that the bending strength of the samples increases with increase in substitution and also with the increase in mould presure. With a value of 45 MPa the bending strength of the samples containing 15 wt% sintered at a temperature of 1100 oC were higher than the standard porcelain. This could be attributed to compaction and sharp microstructural changes.
