Optimization of fritting parameters of ceramic frits: effect on the rheological behavior of the glaze suspensions.

Studies to optimize the prepn. parameters used in industrial frits are reported. Two frit compns. widely used for the prodn. of single-fired ceramic-glazes were chosen: an alk. boric and an earth-alk. boric compn. The chem. durability and rheol. behavior of the frit suspensions were studied in relation to changes in the fritting temp. and time. The results confirm that the two frits studied react differently to changes in fritting parameters due to the dependence on their chem. durability and compn. Suspensions prepd. with the alk.-boric frit displayed no significant change in their rheol. properties; the earth-alk.-boric frit suspensions were more markedly affected.
