Cheap Semiconductor Industry Electronic Grade Cylinder Wf6 Gas Tungsten Hexafluoride

Product Description

WF6 refers to tungsten hexafluoride, which is a chemical compound consisting of one tungsten atom bonded to six fluorine atoms. Here are some key points about WF6:

1. Chemical Formula: WF6
2. Molecular Weight: 297.84 g/mol
3. Structure: WF6 has an octahedral molecular geometry, with the tungsten atom at the center and six fluorine atoms arranged around it.
4. Physical Properties: Tungsten hexafluoride is a yellowish gas at room temperature. It has a boiling point of approximately 17.1°C (62.8°F) and a melting point of -2.5°C (27.5°F).
5. Applications: WF6 is primarily used in the production of tungsten metal and tungsten alloys through a process known as chemical vapor deposition (CVD). In CVD, WF6 is decomposed in the presence of hydrogen gas to deposit tungsten onto a substrate, forming a thin film. This technique is widely employed in the semiconductor industry for the fabrication of microelectronic devices.
6. Toxicity: Tungsten hexafluoride is highly toxic and corrosive. It can cause severe burns to the skin, eyes, and respiratory system upon contact. Proper handling procedures and protective equipment, such as gloves and goggles, should be used when working with WF6.
7. Reactivity: WF6 is a highly reactive compound. It readily reacts with water, moisture, and other reactive substances, releasing toxic hydrogen fluoride gas (HF). Therefore, it should be handled and stored away from moisture and incompatible materials.
8. Safety Considerations: Due to its toxicity and reactivity, the use and handling of WF6 require strict safety protocols. Proper ventilation, personal protective equipment, and containment systems should be in place to minimize exposure and prevent accidental releases.
9. Environmental Impact: Tungsten hexafluoride is not considered a significant environmental pollutant. However, appropriate disposal methods should be followed to prevent its release into the environment.
10. Regulations: The use and transportation of WF6 may be subject to regulations and restrictions imposed by local authorities or regulatory bodies. Compliance with these regulations is necessary to ensure safe handling and minimize environmental impact.
