Tungsten Seed Holder for Sapphire Growth

High-Purity Tungsten Seed Holders for Sapphire Growth Product Overview The Tungsten Seed Holder is a critical component within the Hot Zone Of Sapphire Growth furnaces, responsible for securely gripping the sapphire seed crystal at the start of the crystal pulling process. Its performance is paramount to achieving a high-quality, single-crystal boule. We manufacture high-purity, precision-machined tungsten seed holders that offer exceptional thermal stability, high-temperature strength, and resistance to deformation. Our seed holders are engineered to ensure a stable and reliable growth process, minimizing defects and maximizing yield for manufacturers of sapphire used in LEDs, watch faces, and semiconductor substrates. Technical Specifications Parameter Specification Material High-Purity Tungsten (W ≥ 99.95%) Operating Temperature Stable up to 2200°C Density ≥ 19.1 g/cm³ Design Custom manufactured to fit Kyropoulos (KY), Czochralski (CZ), and other furnace types Key F…
