What Are Applications of Tungsten Crucible?
CTIA's tungsten crucible serves as high-purity refractory metal container made of premium tungsten (W ≥ 99.95%). Characterized by high melting point, low vapor pressure, exceptional high-temperature strength, and excellent thermal stability, it operates reliably in vacuum or inert atmospheres exceeding 2000°C for extended periods.
With melting point of approximately 3410°C, tungsten maintains structural stability under extreme temperatures, making tungsten crucible highly applicable across crystal growth, vacuum coating, metallurgy, and high-temperature material preparation.
