Octafluoropropane
八氟丙烷(C3F8)是一种无色、无味、不可燃的惰性气体。八氟丙烷熔点为-183.0℃，沸点为-36.7℃，难溶于水。电子级高纯八氟丙烷应用在半导体器件制造过程中，与氧气的混合气可用作等离子蚀刻气体。
Octafluoropropane (C3F8) is a kind of colorless, odorless, non-flammable inert gas. Its melting point is 183.0 ℃, boiling point is 36.7 ℃, poorly soluble in water. Electronic grade octafluoropropane is used in semiconductor materials and semiconductor device manufacturing. The mixture of octafluoropropane and oxygen is used as plasma etching material, which can selectively interact with the metal matrix of silicon wafer.
