Tungsten Crucibles for Sapphire Crystal Growth Furnaces: The Core Component for High-Temperature Crystal Growth
In large-scale sapphire crystal production, the high-temperature container inside the growth furnace directly determines crystal quality. Tungsten crucibles, with their excellent high-temperature stability, have become essential consumables in the heat exchange method for sapphire crystal growth. Sapphire crystals must be grown in extreme conditions exceeding 2000°C, where raw materials are melted and crystals are formed. Conventional metal materials tend to deform, volatilize, or contaminate the melt under such conditions. In contrast, tungsten crucibles provide reliable support for growing large-size, low-defect sapphire crystals due to their high melting point, superior strength, and chemical inertness.
