The Effect of Ash-Slag on Drying of a Ceramic Sample Based on Non-Ferrous Metallurgy Waste

Abstract

Introduction of ash-slag into the ceramic composition as a desiccant, which is a non-shrinkable material, contributes to a more uniform moisture distribution within a sample and its effective removal during drying. This also has a positive effect on ceramic product molding and drying processes. Ash-slag must be introduced into ceramic masses to reduce shrinkage during drying, increase moisture conductivity, however, it should be borne in mind that this reduces the ceramic product strength under compression. Optimum compositions for effective drying contain 20 – 24 % ash slag. A regression analysis method is used to predict the results that are not provided in an experiment.
