This Crystal Growing Furnace is a compact crystal grower for both CZ and Bridgeman methods up to 1100°C. The precision pulling & rotation mechanism is built on a compact two-zone vertical tube furnace with 2" quartz tube and vacuum-sealed flange, which can pull a single crystal from a melt in the crucible via seed or move down to grow the crystal via a capillary.This technique is used to grow single crystals of semiconductor materials (silicon, germanium and gallium arsenide), metals, salts and synthetic gemstones.
Specifications
