Long‐term crystal growth experiments were successfully performed under microgravity conditions during the first flight of the unmanned mission EURECA‐1 in the automatic mirror furnace (AMF). Two crystals of Al x Ga 1−x Sb with [001] and [111] orientation respectively were grown from gallium solution by the travelling heater method. The grown length of the single crystals is 4.0 mm and 4.2 mm respectively. The space‐grown samples show a high microscopic homogeneity which indicates the absence of time dependent convection. From pulse markers a constant growth rate of 0.6 ± 0.1 μm/min is measured which is lower than 0.8 ± 0.1 μm/min obtained in earth grown reference samples. Details about the experiment performance and the growth results are given.
