Abstract Scope This research examines the influence of soda-lime-silica glass on the porosity, crystallization and phase transformation of ceramics produced from white corn cob ash. The Corn cobs (CCB) and soda-lime-silica glass (SLSG) are both agricultural and industrial wastes which when sent to landfills constitute environmental challenges. These wastes are however both sources of silica and can be recycled to produce piezoelectric based ceramics materials. The corn cob was subjected to thermal combustion in open air to yield amorphous silica and then conditioned to 700C for 6hrs before screening. A mixture of CCBA and SLSG were mixed in a ball mill and then pressed into pellets using polyvinyl alcohol (PVA) as binder and then sintered at 900C, 1000C and 1200C respectively. SEM result shows that, as the sintering temperature increases the porosity of the samples decreased. XRD and FTIR results revealed a cristobalite dominant phase and chemical bonds formed in the material.
