Description
Summary:Improving the technological properties of a ceramic product without affecting its aesthetic quality is a daily challenge of the regionalceramic companies. To achieve this objective, analyzes were performed on an illitic-kaolinitic clay by adding corundum as anadditive. The corundum content varied from 5% to 20% by weight with a particle size of less than 75 μm, being able to obtain productswith low porosities and high mechanical resistance. This research is part of a series of studies carried out on an argillaceous rawmaterial from the region of Norte de Santander (Colombia). The influence of the corundum content on the technological propertieswas evaluated. The results showed that corundum, when mixed with traditional raw materials, offers the conditions to be used asan additive in the production of ceramic products with increases of up to 67% in mechanical strength and a reduction of porosity of46%, which can contribute to the development of value-added ceramic products for use in other technological applications.
