The metastability of the bixbyite‐ and corundum‐type In 2 O 3 polymorphs up to 33 GPa (at room temperature) is shown. While compressed (in diamond anvil cells) and laser‐heated, both polymorphs undergo a phase transition to the Rh 2 O 3 ‐II‐type structure (space group Pbcn , No. 60). The direct transition from bixbyite to Rh 2 O 3 ‐II structure has not yet been observed for any other oxide.(© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
