    Abstract: A method and apparatus for growing truly bulk In2O3 single crystals from the melt, as well as melt-grown bulk In2O3 single crystals are disclosed. The growth method comprises a controlled decomposition of initially non-conducting In2O3 starting material (23) during heating-up of a noble metal crucible (4) containing the In2O3 starting material (23) and thus increasing electrical conductivity of the In2O3 starting material with rising temperature, which is sufficient to couple with an electromagnetic field of an induction coil (6) through the crucible wall (24) around melting point of In2O3. Such coupling leads to an electromagnetic levitation of at least a portion (23.1) of the liquid In2O3 starting material with a neck (26) formation acting as crystallization seed. During cooling down of the noble metal crucible (4) with the liquid In2O3 starting material at least one bulk In2O3 single crystal (28.1, 28.2) is formed.
