摘要： The invention relates to a chemical vapor deposition (CVD) method for forming tungsten carbide, W.sub.3 C, by subjecting a gas mixture of tungsten hexafluoride, hydrogen and an aromatic hydrocarbon, e.g. benzene, to vapor phase reaction at an elevated temperature. The reaction temperature can be lowered to the extent of 250.degree. C. and the reaction can be carried out even at normal pressure, not necessarily under reduced pressure, by proportioning tungsten hexafluoride, hydrogen and the hydrocarbon such that in the gas mixture the atomic ratio of C to W falls in the range from 2 to 10 while the atomic ratio of H to C is not lower than 3. By this method a W.sub.3 C film excellent in glossiness can be deposited on various metal parts without adversely affecting the metal parts by the elevated temperature.

摘要： The invention relates to a method for producing nitrogen trifluoride by gas-solid reaction. This method includes the steps of (a) providing a packed-bed-type vessel filled with a particulate solid of an ammonium complex of a metal fluoride; (b) introducing a fluorine-containing gas into the vessel to allow the fluorine-containing gas to flow upwardly through the vessel such that fluorine of the fluorine-containing gas is reacted with the particulate solid in the vessel, thereby to obtain a reaction gas containing nitrogen trifluoride; and (c) separating the nitrogen trifluoride from the reaction gas. A part of the reaction gas flowing out of the vessel may be introduced into the vessel, and thereby circulated through the vessel. The yield of nitrogen trifluoride becomes substantially improved by this method.
