Customized Tungsten Crucible
Customized tungsten crucible is non-standard, high-temperature resistant container manufactured from high-purity tungsten materials through processes such as sintering, forging, spinning, welding, or precision machining. Featuring excellent structural stability and thermal uniformity, it is engineered to precisely match the requirements of specialized thermal fields and complex working conditions. It is widely utilized in cutting-edge fields such as sapphire crystal growth, high-purity metal smelting, vacuum evaporation coating, and semiconductor material preparation.
Performance Characteristics of CTIA's Customized Tungsten Crucible
(1) High-Temperature Stability: The high melting point and low vapor pressure of tungsten enable the crucible to operate stably for extended periods in vacuum or inert atmospheres at temperatures ranging from 1800°C to 2600°C.
(2) High Strength and High Density: The high-density structure provides excellent mechanical strength and thermal shock resistance, ensuring superb dimensional stability even for complex, custom-shaped structures.
(3) Low Contamination Risk: The combination of high-purity materials and a smooth surface finish effectively minimizes the risk of impurity contamination and material reactions, making it ideal for the preparation of high-purity metals and crystal materials.
Applications of CTIA's Customized Tungsten Crucible
(1) Sapphire Single Crystal Growth: Used in crystal growth furnaces (such as those utilizing the Kyropoulos method) to provide a uniform temperature field, reduce impurity contamination, and improve crystal quality.
(2) Rare Earth and High-Purity Metal Smelting: Serving as high-temperature and corrosion-resistant vessel for the smelting and purification of metals such as tungsten, molybdenum, tantalum, niobium, titanium, lanthanum, cerium, praseodymium, and neodymium.
(3) Vacuum Evaporation Coating: Utilizing the crucible as evaporation vessel in electron beam evaporation and thermal evaporation systems.
(4) Semiconductor Material Preparation: Used for material synthesis, crystal growth, and thermal field control in high-temperature vacuum environments.
(5) High-Temperature Ceramic Sintering and Glass Melting: Used in high-temperature sintering and melting processes under complex thermal field conditions, maintaining excellent structural stability and thermal uniformity.
(6) Aerospace, Nuclear Energy, and Scientific Research: Employed in experiments and production lines involving specialized geometric structures and extreme high-temperature conditions.
