VGF Crucible (Vertical Gradient Freeze Crucible) is a key container for growing compound single crystals using the Vertical Gradient Freeze (VGF) method. It is primarily used to hold molten polycrystalline materials and enables controlled crystal growth by precisely managing the temperature gradient, allowing the material to solidify gradually from bottom to top. It is widely used in the field of semiconductor single-crystal growth.
Applications:
Supporting Molten Materials：
Holds semiconductor polycrystalline materials such as GaAs and InP, compatible with heating systems to ensure uniform melting.
Assisting Directional Solidification：Utilizes high-temperature resistance and low-contamination properties, working with temperature control to create a vertical thermal gradient that guides the melt to solidify slowly from bottom to top into a single crystal.
Ensuring Single-Crystal Quality：Made from high-purity inert materials to prevent reactions and impurity introduction, reduce melt evaporation, and ensure high-purity, low-defect single crystals.
Adaptable to Different Specifications：Customizable in volume and size, suitable for both laboratory research and industrial production, meeting the growth requirements of single crystals with diameters from 2 to 6 inches.
