Depending on the type of gas used, these layers form when precursor gases react with heat or basic gases such as as hydrogen. 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 silicon-germanium alloys.

Next, mill operators thicken the slurry with water to form pulp and run the pulp through a series of leaching tanks. Leaching dissolves the gold out of the ore using a chemical solvent. The most common solvent is cyanide, which must be coined with oxygen in a process known as carbon-in-pulp. As the cyanide and oxygen react chemically, gold in

What Is Metal Active Gas (MAG) Welding?

05/04/2021· MAG welding uses an active gas that makes it react well with construction steels and thick to medium-thick sheet metal. MAG welding produces intense heat, which can cause the CO 2 to split into carbon monoxide and oxygen. This can cause partial oxidation, which is why MAG is not used for welding light steels or alloy metals.
