  • Method for production of trichlorosilane and silicon for use in the production of trichlorosilane
    Patent number: 7462341
    Abstract: The present invention relates to a method for the production of trichlorosilane by reaction of silicon with HCl gas at a temperature between 250 and 1100° C., and an absolute pressure of 0.5-30 atm in a fluidized bed reactor, in a stirred bed reactor or a solid bed reactor, where the silicon supplied to the reactor contains between 30 and 10.000 ppm chromium. The invention further relates to silicon for use in the production of trichlorosilane by reaction of silicon with HCl gas, containing between 30 and 10.000 ppm 10 chromium, the remaining except for normal impurities being silicon.

  • Method for removing impurities from silicone-containing residues
    Publication number: 20040220421
    Abstract: The present invention relates to a method for removing impurities from elemental silicon-containing residues from the processes of producing organochlorosilane and chlorosilane. The residues are subjected to magnetic seperation to provide a relative pure non-magnetic fraction having an increased silicon content and a relatively impure magnetic fraction having a lower silicon content than the non-magnetic fraction.
