The Fluxing action of Lithia (Li2O) was investigated by addition of Lithium Carbonate and Spodumene to sanitary ware body. Rectangular specimens were prepared by Slip Casting method prior to firing at 1150?C and 1200?C. The effect of Lithium oxide in sanitary ware body was found to be favorable for reducing maturing temperature up to 50?C. The presence of lithia reacting with other oxides and silicates formed a liquid phase of lower viscosity, which accelerated the densification through viscous flow sintering, without compromising the mechanical strength. Phase development of the fired bodies were also discussed and well correlated with the final properties. Lowering the sintering temperatures leads to reduction in fuel consumption and environment harmful gases.
