(57) Abstract: (Corrected) A method for producing a mixture of phosphine and one or more diluent gases, a novel metal phosphide composition suitable for carrying out the method, and the method are carried out. Providing generators for SOLUTION: A hydrolyzable metal phosphide selected from the group consisting of magnesium phosphide, aluminum phosphide and calcium phosphide is brought into contact with liquid water in the production space to hydrolyze the metal phosphide. To release phosphine, where the phosphine is removed from the production space and, where appropriate, diluted with a diluent gas from the time of its production to its point of use, under conditions of use. In the case of an ignitable composition and when the dilution has already started in the production space, the hydrolysis comprises a carrier gas inert to phosphine which constitutes at least part of the diluent gas. By doing in an atmosphere, Produce a mixture of phosphine and one or more diluent gases. |
