Abstract
The high temperature, apparently tetragonal, polymorph of tantalum pentoxide can be obtained at room temperature by quenching a specimen containing 2-5 mole percent of the following oxides: SnO2, Ga2O3, Cr2O3, Fe2O3, Sc2O3, or MgO. All the x-ray patterns can be indexed on a body centered tetragonal cell with a ? 3.830 ?, c ? 35.68 ?. However, P2O5, V2O5, Nb2O5, ZrO2, Lu2O3, NiO, or ZnO do not stabilize the tetragonal form at room temperature. Single crystals of scandium 'stabilized' Ta2O5, have been grown by the Czochralski technique.
