Abstract
Method of preparing metal disulfides of the general formula EQU (Sn.sub.x Me.sub.1-x)S.sub.2, wherein PA1 Me represents one or more of the elements Ti, Mo, Fe, Cr, Ta, Nb, Mn, Bi, W and Cu, and PA1 x can have values between 0.5 and 1, PA1 by mixing Sn, alone or with Me and/or Me sulfides, with a superstoichiometric quantity of S and reacting the same together, in the presence of halide compounds, in an exothermic reaction in an inert atmosphere and the further processing the disulfide product thereof to form dimetal trisulfides.
