The influence of metallurgical slurries on drying behaviour of ceramic masses for lining brick production

The influence of metallurgical slags on the drying properties of ceramic masses has been investigated. It has been experimentally established that the use of fine-grained slag helps to reduce the sensitivity of clay raw materials to drying. It was confirmed by electron microscopy, infrared spectroscopy and simultaneous thermal analysis that the slag grains have a highly developed porous surface, as a result of which part of the water introduced during the formation of ceramic masses is adsorbed on the surface of the slag grains. The role of fine-grained metallurgical slag in ceramic masses as a highly effective lean component is shown.
