The high average thermal expansion required for thermal compatibility of dental porcelains with their substrate alloys is supplied by the mineral leucite (K2O Al2O3 4SiO2). Since leucite is not an equilibrium phase at the composition of component No. 1 of the Weinstein et al. patent, phase changes in this leucitecontaining frit could be responsible for the observed thermally induced changes in dental porcelain expansion behavior. This study sought to explore such phase changes.
