Abstract (en)

[origin: WO2010149545A1] The invention relates to a method for producing oligohalogen silanes, selected from oligohalogen silanes of the general formulas (1) and (2): SinX2n+2 (1), SimX2m (2), wherein a mixture comprising silicon and metal halogenide selected from Ti, Zr, Hf, V, Nb, Mo, W, Fe, Co, Ni, Gu, Cd, In, Sn, P, Sb, Bi, S, Se, Te and Pb and mixtures thereof is converted at a temperature of -125°C to 1100°C and the oligohalogen silanes formed are removed by means of a carrier gas selected from N2, noble gases, CH3C1, HC1, CO2, CO, H2, and SiC14, where X is selected from C1, Br and J, n is a whole number from 2 to 10, and m is a whole number from 3 to 10.
