SANCHEZ-MUNOZ, L. et al. Modelling of the vitrification process of ceramic bodies for whiteware. Cerâmica [online]. 2002, vol.48, n.308, pp. 217-222. ISSN 0366-6913. http://dx.doi.org/10.1590/S0366-69132002000400009.
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.
