Abstract
We have invented the traveling liquidus-zone method for growing homogeneous mixed crystals. In this method, the solute transport rate is controlled by the temperature gradient at the freezing interface and compositional homogeneity is established easily on the ground, although the actual growth rate is affected by convection in the liquidus zone. Growth rates for producing homogeneous crystals are examined experimentally by changing the temperature gradient in the zone and they are analyzed theoretically. Experimental results agree with numerical analysis qualitatively.
