Modelamento do processo de gresificação de massas cerâmicas de revestimento

A model was proposed for the vitrification process of ceramic bodies for porcelain stoneware tiles, based on the correlation among the porosity and the mixture components and its evolution with temperature. The application of the model was accomplished using a frit especially designed as flux and an optimized composition of clay and kaolin. Accordingly, a porcelain stoneware tile body for low firing temperature (~ 1150 oC) and a dimensional stability range of approximately 100 oC has been developed.
