Abstract

The thermal anomalies associated with the Ia3d → I41/acd → I41/a transition sequence of phase transitions in leucite have been studied by differential scanning calorimetry and interpreted with Landau theory. Both transitions are close to the tricritical point. The coupling between the two transitions is biquadratic, and reduces the stability of the I41/a phase.
