Products Description
Tungsten crucible cover is made of pure tungsten which is one part of tungsten crucible. The tungsten crucible for sapphire growth furnace is used the material of tungsten with the purity over 99.95%. Mostly, tungsten crucible cover is sintered, and its density is about 18.3g/cm3. Also, tungsten crucible cover, the complete set products include tungsten crucible base, or tungsten tray.
As the heat shield parts of sapphire growth furnace, the most important efforts made by tungsten crucible cover and tungsten heat shield are sealing the products inside the furnace and keeping the temperature inside. Tungsten crucible cover is hgh purified, high specifications accuracy, smooth surface condition and reasonale design, which are important for the quality of sapphire crystal.
Tungsten crucible cover and tungsten crucible closely integrated to provide a sealed space for the production of sapphire crystal. The seal of space control is a key factor for the quality of the sapphire crystal sapphire growth.
features
High Temperature Resistance: Tungsten has a very high melting point of 3422°C. Therefore, the Tungsten Crucible Cover can work stably in high-temperature crystal growth furnaces without deforming or breaking.
High Purity and Low Contamination: High-purity tungsten material reduces the impact of impurities on crystal growth. This ensures the purity and quality of the crystals.
Corrosion Resistance: During crystal growth, high temperatures and complex chemical reactions are common. The crucible cover can resist corrosion, which extends its service life.
Good Mechanical Properties: It has high strength and hardness, so it can withstand certain mechanical stress.
High Dimensional Accuracy: The manufacturing process strictly controls size precision. This ensures a tight fit with the crucible and prevents gas leakage.
applications
Crystal Growth: In sapphire single crystal growth furnaces, the Tungsten Crucible Cover is an essential part. It provides a stable high-temperature environment for crystal growth and ensures uniform crystal formation.
Metallurgical Industry: It can be used in the melting and casting of high-temperature alloys and metals, offering a stable container environment.
Semiconductor Manufacturing: During the production of semiconductor materials, such as silicon single crystal growth, the Tungsten Crucible Cover is used to melt and hold high-purity materials.
Chemical Processing: In chemical synthesis, refining, and purification, it is used to contain and heat highly corrosive chemicals and molten salts.
