Abstract
The authors carried out a study to investigate the behaviour of three industrial bodies (two monoporosa bodies and one double firing body) which differ principally in their carbonate content. Moreover four different binary mixtures containing illitic or kaolinitic clay and calcite or dolomite were prepared to investigate their reactivity during firing. In this study it has been observed that ghelenite and anorthite were formed in all samples as new phases and MgO residues remain inside monoporosa and fast double firing products after heat treatment in the sample containing dolomite.
