Improved rheological characterisation of ceramic slips and glazes using zeta potential measurements

Objective



The characterisation and quality control of materials used in the whitewares industry for production processes is critical to ensure high yields. At present the ceramic industry relies heavily on the preparation, processing and use of a wide variety of aqueous suspensions of clay and mineral powders. Currently the rheology of these is controlled by torsion viscometry and density data but these methods are somewhat crude and often give poor results. By the use of Zeta Potential as a quality control and research tool it is intended to reduce losses caused by the use of unsuitable products.
