Abstract: The effect of solvents ethyl methyl ketone (MEK), toluene, xylene and ethanol on the properties of thin films of zirconia prepared by the tape casting technique is reported here. It has been found that preparation of the slurry for tape casting plays an important role in controlling the textural properties of the membranes. The rheological features of the cast tapes are satisfactorily related to the solvent ratio. The toluene + xylene solvent system has been found to provide fine casting and sintering. The physical characteristics of the green tapes like thickness, density and weight losses during sintering have also been measured. The rate of heating is determined by TGA analysis of the green tapes. The role of solvents in controlling the properties of tape cast zirconia membranes is also described.
