Tungsten metal crucible is one of the metal tungsten products, mainly divided into sintering molding (applied to powder metallurgy technology), stamping molding, and spinning type. It is formed by turning tungsten rods (generally the size is relatively small), and there are many kinds of welding shapes. It is made of pure tungsten plates, tungsten sheets, and pure tungsten rods through corresponding processes. Tungsten crucibles can be used in vacuum inert gas below 2600 degrees. Tungsten metal crucibles produced by Baoji Yusheng Metal Technology Co., Ltd. are widely used in rare earth smelting, quartz glass, electronic spraying, crystal growth, and other industries.
Since the melting point of tungsten is as high as 3410°C, tungsten crucibles are widely used as core containers in industrial furnaces such as sapphire single crystal growth furnaces, quartz glass melting furnaces, and rare earth smelting furnaces. The working temperature environment is generally above 2000°C. Especially for sapphire single crystal growth furnaces, tungsten crucibles with high purity, high density, no internal cracks, precise dimensions, smooth inner and outer walls, etc. have a great influence on the seed crystal success rate, crystal pulling quality control, Decrystallization sticky pan and service life play a key role.
There are two main types of tungsten metal crucible products. One is a small crucible made of tungsten rods through mechanical processing and other processes. It is mainly used in electronic industries such as vacuum coating. In addition, it can be sintered into a rough billet by powder metallurgy and then processed into a large crucible, which is mainly used in the sapphire industry. All kinds of tungsten metal crucibles produced by our company have mature technology and stable product quality.
