Tungsten Crucible in Nuclear Materials Testing
Tungsten crucible in nuclear materials testing refers to the ultra-high-temperature refractory vessel manufactured from high-purity tungsten material (W≥99.95%), which features high melting point (3422°C), low vapor pressure, excellent high-temperature strength, and good thermal creep resistance. Under high-temperature vacuum or inert atmosphere, tungsten crucibles maintain stable structural properties and thermal field uniformity. They are primarily utilized for melting, sintering, and thermal field research of nuclear materials, high-purity rare metals, radioactive material simulation systems, and related high-temperature experimental environments in the nuclear industry.
Why use tungsten crucibles for nuclear materials testing? Nuclear materials testing typically involves high-temperature sintering, vacuum melting, thermal stability analysis, and material phase transition research, which demand high-temperature strength, dimensional stability, and thermal cycling resistance from the vessel materials.
With over 30 years of manufacturing experience, CTIA GROUP provides high-purity tungsten crucibles produced through various processing routes including sintering, spinning, forging, and precision machining, all of which are customized to different experimental equipment and thermal field conditions to meet diverse temperature ranges and service life requirements. Strengthened by high-temperature plastic deformation, the internal grain structure of the crucible becomes denser, highly resisting deformation under long-term high-temperature cycling environments. For high-temperature vacuum furnaces, electron beam heating systems, and induction melting equipment, CTIA can further optimize the bottom thickness, wall thickness uniformity, and concentricity to enhance thermal field stability and experimental reproducibility.
