Florcanasite glass ceramics are of interest as materials for aesthetic dental restorations. In an attempt to control the solubility of a fluorcanasite glass ceramic, systematic additions of SiO2 and AlPO4 were made. Solubility was reduced from 2359 to 624 mgcm-2. There was an initial increase in biaxial flexural strength, 123-222 MPa with small additions; however, larger additions reduced the strength to 147 MPa. These findings were attributed to there being an increased volume fraction of residual glassy matrix.
