Large Size Tungsten Crucible
Large size tungsten crucible is large-specification, high-temperature resistant container manufactured from high-purity tungsten materials through processes such as powder metallurgy sintering, forging densification, spinning forming, and precision machining. Featuring excellent structural stability and thermal load-bearing capacity, it maintains shape stability and uniform temperature distribution in large-volume, high-temperature thermal fields, making it suitable for high-end industrial scenarios requiring large-scale thermal zones and high-load operations.
Characteristics of CTIA's Large Size Tungsten Crucible
(1) High-Temperature Adaptability: The high melting point of 3422°C and low vapor pressure of tungsten enable the crucible to operate stably in vacuum or inert atmospheres at temperatures ranging from 1800°C to 2600°C.
(2) High Density and Strength: The high-density structure provides excellent thermal shock resistance and mechanical strength, ensuring long-term structural stability under large dimensions.
(3) Purity Control Capability: High-purity tungsten materials combined with a smooth surface finish effectively reduce melt contamination, guaranteeing high purity of crystals or metals.
(4) Thermal Field Uniformity: The large-capacity design combined with good thermal conductivity forms a uniform temperature field, enhancing crystal growth quality and process repeatability.
Applications of CTIA's Large Size Tungsten Crucible
(1) Sapphire Single Crystal Growth: Used in large-size crystal growth furnaces to stably support high-temperature melts and optimize thermal field distribution, thereby increasing crystal size and quality.
(2) High-Purity Metal Smelting: Used in large-scale high-temperature smelting and purification processes of materials such as tungsten, molybdenum, tantalum, niobium, and rare earth metals, improving melt purity and uniformity.
(3) Vacuum Heat Treatment: Used in large vacuum heat treatment equipment to achieve high-temperature sintering and material structure optimization.
(4) Semiconductor Material Preparation: Used for large-size crystal growth and high-temperature material synthesis processes, improving thermal field stability and consistency.
(5) High-Temperature Scientific Research: Used in large-volume high-temperature reactions and material thermal behavior research to meet complex experimental needs.
