✦ Synopsis
Long-term crystal growth experiments were successfully performed under microgravity conditions during the first flight of the unmanned mission EURECA-I in the automatic mirror furnace (AMF). Two crystals of A1,rGal_,Sb with [OOI] and [I I I ] 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 f 0.1 pmlmin is measured which is lower than 0.8 f 0.1 pmlmin obtained in earth grown reference samples. Details about the experiment performance and the growth results are given.
