Influence of the clay type on the pore structure of structural ceramics

The formation of the microstructures of ceramic bodies during firing depending on the clay type will be presented. Through the separation of four different clay types the microstructural development during firing could be systemised. With regard to the hygric behaviour such as capillary suction and humidity absorption as well as to the durability the clay type depending pore structures will be discussed. The influence of the utilisation of industrial wastes in ceramic bodies on their microstructure will be introduced by first results of a current research project and are exemplified by one clay type.
