  • Bicameral mode crystal growth apparatus and process
    Patent number: 4379733
    Abstract: An apparatus and process for growing large single halide crystals that are ultra pure is described. A bicameral apparatus and process is employed in which the crystals are grown in a reactive chamber positioned within an inert chamber. A radial seal is provided on the furnace chamber to facilitate the reaction and maintenance of an inert atmosphere around and about a crystal growth assembly wherein crystals are grown from a melt under a reactive atmosphere.
