| Abstract: | This article describes the selection and optimization of dispersant dosage in colloidal processing of ceramic slurry by techniques such as particle charge detector (PCD), capillary suction time (CST), rheological measurement, and wet point and flow point techniques. In general, experimental results are found to be in good agreement with each other with some degree of variation. PCD, CST, and rheological techniques are related by a simple linear function. The experimental and calculated values are well matching within an error limit of 10%. Attempt has been made to develop formula for correlating results of optimization from one technique to those obtained from another technique. The region where the suspension is well dispersed, CST is linearly correlated with PCD. The advantages and limitations of each technique have been described and discussed. |
