The CYSI 1650°C Bridgman Crystal Growth Furnace provides precise thermal gradient control for directional solidification and single crystal growth of sapphire (Al₂O₃), silicon nitride (Si₃N₄), yttrium aluminium garnet (YAG), and other oxide and nitride crystals. The independently controlled hot zone and cold zone with programmable withdrawal speed deliver reproducible crystal growth rates and minimal grain boundary density for research and small-scale production applications.
