In 1811 Gay-Lussac and Thenard probably obtained impure amorphous silicon by heating potassium with silicon tetrafluoride; however, the discovery of this element is usually credited to Berzelius ...

After evacuating the air, a small amount of fluorinated gas — either carbon tetrafluoride or the always entertaining sulfur hexafluoride — is added to the chamber. A high-voltage feedthrough ...

The fuel salt, operating at a maximum temperature of 650C, will contain a mixture of lithium fluoride, beryllium difluoride, and uranium tetrafluoride (LiF-BeF2-UF4 with a molar ratio of about 67: ...

This led the team to investigate using a new click ‘connecting hub’ – thionyl tetrafluoride gas (SOF 4). This ‘hub’ molecule was first reported in 1902 and has four replaceable fluoride sites for ...

Many halides—including silane, silicon tetrachloride, and silicon tetrafluoride—are employed as silicon precursors. Some specialty gases such as germane (GeH 4) are also used to form and deposit ...
