Suppression of Anomalous Allotropic Transformations at High Pressures

  • Published:
Inorganic Materials Aims and scope

Abstract

Anomalous allotropic transformations accompanied by a reduction in the density of the substance can be suppressed by applying a high pressure equal to the ratio of the heat of transition to the difference in the volumes of the phases involved. The estimated pressures necessary to suppress the β → α (ZrO2), γ → α (Fe), and β → α (Sn) phase transitions are 4.34, 3.00, and 0.495 GPa, respectively.
