    摘要： Fluorine is recovered as calcium fluoride from a fluoroetchant solution composed mainly of hydrogen fluoride and ammonium fluoride using a sealed reaction tank equipped with a supply port for adding the fluoroetchant solution to the tank, a supply port for adding calcium carbonate to the tank, a vapor supply port for adding steam to heat the solution in the tank, an air supply port for providing air to aerate the contents of the tank, a stirrer for stirring the contents of the tank, an ejector for removing vapors from the tank connected to the tank via a mist separator for separating mist from the vapors being removed from the tank, and an exhaust port for removing calcium fluoride from the tank.

    摘要： An industrial material such as metal, ceramics or plastics whose surface has a film passivated by fluoridation and a process of manufacturing the above industrial material. The industrial material comprises a substrate, a nickel alloy film formed on the substrate and containing nickel, semimetal and/or other metal whose fluoride becomes a volatile compound, and a fluorine passivated film formed at least on a surface of the nickel alloy film in such a manner that the fluorine passivated film contains nickel and does not contain said other metal or the semimetal, and satisfies stoichiometric ratio. The process of manufacturing an industrial material comprises the steps of performing grounding treatment of a surface of a substrate, forming a nickel alloy film, on the surface of the substrate, containing nickel, semimetal and/or other metal, and forming a fluorine passivated film on the nickel alloy film.
