Traveling Liquidus Zone (TLZ) method enables us to grow compositionally uniform bulk mixed crystals. The driving force of crystal growth in the TLZ method is diffusion and hence convection in a melt affects crystal quality. Results of four space experiments in which convection in a melt was suppressed are compared with terrestrial experiments and effects of convection in a melt on crystal quality were made clear.
