Tungsten crucibles have a high melting point of 3420ºC and are typically used in extreme operating environments above 2400℃. They are extensively utilized in various industries such as sapphire crystal growth, quartz glass melting, vacuum coating, and rare earth smelting. In particular, for the sapphire single crystal growth furnace, the use of high-purity tungsten crucibles with precise dimensions, smooth inner and outer walls, and no internal cracks is critical to achieving optimal seed crystal quality control, de-crystal sticky pot, and extending their lifespan.
