Indium Oxide (In2O3)

Indium Oxide (In₂O₃) has a high melting point (MP) and is highly unstable at high temperatures. The solution techniques utilized to grow bulk In₂O₃ crystals include hydrothermal, flux, and salt electrolysis. A few studies on the growth of bulk In₂O₃ crystals by the hydrothermal method were reported. Chase noticed that In₂O₃ crystals grown from the flux have habit at high supersaturation modified by small faces at low supersaturations, because faces are more stable at high supersaturations, while at low supersaturations. The underlying concept for growing In₂O₃ crystals from the melt is based on a problem inversion, i.e., on using the decomposition of In₂O₃ as a driver for melting and crystallization. The eddy current flowing through liquid In₂O₃ in the vicinity of the crucible wall induces its own electromagnetic field that opposes the electromagnetic field being the source for the eddy current in the crucible.
