Continuous phase transitions were found to occur in ZrTiO 4 above and below a major discontinuity at 1125°±10°C. The space group of both forms of ZrTiO 4 is Pcnb. For specimens quenched from high temperatures, the volume of the unit cell decreases linearly from ∼1450°C to the discontinuity, with the major change occurring in the c axis. The volume decreases considerably at this temperature and continues to decrease with lower‐temperature annealing. Substitutional tin in solid solution stabilizes the high‐temperature structure type.
