Tungsten Crucible Applications
For tungsten crucible applications, Tungsten crucible is mainly used in metallurgical industry, mechanical processing industry, glass and ceramic industry and other fields.
Tungsten crucible is one of tungsten products. Tungsten crucible is mainly divided into sintering type tungsten crucible, stamping type tungsten crucible, welding type tungsten crucible and spinning type tungsten crucible. In addition, there are also tungsten crucibles which are made by molybdenum bar turning processing.
Tungsten crucible is made of pure tungsten plate, tungsten sheet and pure tungsten bar by adopting appropriate processing technology. Tungsten crucible can be applied in vacuum and inert gas under 2600℃.
Tungsten is featured by high melting point and boiling point, good hot strength, excellent wear and corrosion resistance, good thermal conductivity, small coefficient of thermal expansion and good hardenability. Tungsten is widely applied in rare earth smelting, quartz glass, electron, flame plating, crystal growth and other industries.
Next, how to clean the oxidizing material on the surface of molybdenum rod?
The surface of molybdenum rod will form dark oxidizing material after the high temperature burning of oxyhydrogen flame. Now, it is needed to clean the oxidizing material. It is better to soak molybdenum rod in some chemical agents to dissolve the oxidizing material. Then is there any solutions?
At room temperature, molybdenum is stable in the air. At 500℃, molybdenum is able to react with oxygen to generate molybdenum trioxide. So the oxidizing material on the surface of molybdenum rod is molybdenum trioxide. Molybdenum trioxide is slightly soluble in hydrochloric acid and is easily soluble in hot concentrated sulfuric acid and concentrated nitric acid. Molybdenum trioxide also can dissolve in ammonia water and aqueous alkali. So molybdenum rod can be dissolved in the dilute sodium hydroxide solution to clean the oxidizing material.
