Influence of drying on the final properties of ceramics

Abstract

In the scientific studies the influence of burning regime or composition of formation mix on the final properties of the ceramics is analysed most often. However, drying regime is also of paramount importance in the process of the high quality ceramics production. The formed ceramic samples were dried according to 8 different drying regimes while burning regime was not varied during the investigation. The dried samples were burnt for 24 hours keeping the maximum temperature 1050oC for 3 hours. Later on these parameters were determined experimentally: density, compressive strength, reserve of pore volume, and total open porosity. As the statistical analysis of data was performed, the optimal drying regime of ceramic products is selected.
