The zone melting furnace is a compact crystal growth system for CZ, Bridgman, and zone melting up to 1000℃. The precision pulling & rotation mechanism is built on a compact vertical tube furnace with 1" quartz tube and vacuum-sealed flange, which can pull single crystal from a melt in the crucible via seed or downward to grow the crystal via with a capillary. Applications: zone melt purification, directional solidification, or CZ, Bridgman, and zone melting single crystal growth for metallic material.
