摘要：

Commercially available gases contain residual impurities leading to a background oxygen partial pressure of typically several 10(-6) bar, independent of temperature. This oxygen partial pressure is inappropriate for the growth of some single crystals where the desired oxidation state possesses a narrow stability field. Equilibrium thermodynamic calculations allow the determination of dynamic atmosphere compositions yielding such self-adjusting and temperature dependent oxygen partial pressures, that crystals like ZnO, Ga(2)O(3), or Fe(1-x)O can be grown from the melt.
