Acetylene is the chemical compound with the formula C2H2. The main use of Acetylene is for localized or manual operations such as welding, brazing, cutting, straightening or heating. Acetylene is Also used as precursor for amorphous carbon hard mask in Plasma-Enhanced Chemical Vapor Deposition (PECVD). It also is a carbon source in some silicon carbo-nitride films. Acetylene is used to lubricate the molds used in glass bottle manufacturing processes. A layer of fine soot is applied onto the glass mold, so that the glass article can be easily separated from the mold after cooling down. Acetylene is used as fuel gas in atomic absorption spectrophotometry. ASGT is Pioneer in Acetylene for AAS.
