Tungsten CrucibleProduct Introduction
Tungsten Crucible，asTungsten Cruciblean outstanding representative of its products, relying on its unique physical and chemical properties, it plays an irreplaceable role in many high-temperature industrial fields. It is mainly manufactured through various processes such as sintering, stamping, spinning, and machining and welding of tungsten rods, and can meet the needs of different sizes and shapes.
Material Properties：
-
High Specific Gravity and High Density：Tungsten CrucibleIt has extremely high specific gravity and density, which allows it to maintain excellent stability and durability under high-temperature environments.
-
High Melting Point and High Boiling Point: The melting point of tungsten is as high as 3410℃, and the boiling point is as high as 5900℃, which allowsTungsten Crucibleto work normally at extremely high temperatures without melting or evaporating.
-
Low Vapor Pressure and Low Evaporation Rate: In high-temperature environments,Tungsten Cruciblehas extremely low vapor pressure and slow evaporation rate, ensuring its stability and reliability during long-term high-temperature operation.
-
Low Coefficient of Thermal Expansion：Tungsten Cruciblehas a low coefficient of thermal expansion, meaning that the changes in its size and shape are relatively small during high-temperature changes, which is conducive to maintaining the precision and stability of the workpiece.
-
Corrosion Resistance and Wear Resistance：Tungsten CrucibleIt has good resistance to various chemical corrosive media, and its wear resistance is excellent, allowing it to maintain a long service life under harsh working conditions.
-
Good Thermal Conductivity：Tungsten CrucibleIt has excellent thermal conductivity, allowing it to quickly transfer heat to the workpiece and improve heating efficiency.
In addition, depending on the manufacturing process,Tungsten Cruciblethe density will also vary. The density of forged and sintered tungsten crucibles is greater than 19.35g/cm³ and 18.5g/cm³ respectively, ensuring its stability and durability under high-temperature environments. At the same time, adding a certain amount of rare earth elements during the manufacturing process of pure tungsten crucibles can further improve its oxidation resistance and prolong its service life.
Product Applications：
Tungsten crucibles are widely used in rare earth smelting, quartz glass, electronic spraying, and crystal growth industries due to their excellent performance. In the field of rare earth smelting, tungsten crucibles, as key components of smelting furnaces, can withstand extremely high temperatures and pressures; in the quartz glass melting process, tungsten crucibles, as containers of melting furnaces, ensure the purity and quality of quartz glass; in the electronic spraying industry, tungsten crucibles, as heating elements, provide a stable high-temperature environment for the spraying process; in the crystal growth field, tungsten crucibles, as high-temperature containers, provide key high-temperature environments for single crystal furnaces and sapphire single crystal growth furnaces.
It is particularly noteworthy that, in the sapphire crystal growth process, tungsten crucibles need to have no internal cracks, precise dimensions, and smooth inner and outer walls to ensure the quality and growth efficiency of sapphire crystals.
In summary, tungsten crucibles, with their unique material properties and wide range of applications, have become an indispensable important material in many high-temperature industrial fields.
