  • Method for production of trichlorosilane and silicon for use in the production of trichlorosilane
    Patent number: 9388051
    Abstract: The present invention relates to a method for the production of trichlorosilane by reaction of silicon with HCI 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 40 and 10.000 ppm by weight barium and optionally 40-10000 ppm by weight copper The invention further relates to silicon for use in the production of trichlorosilane by reaction of silicon with HCI gas, containing between 40 and 10.000 ppm by weight barium and optionally 40-10000 ppm by weight copper, the remaining except for normal impurities being silicon.

  • METHOD FOR PRODUCTION OF TRICHLOROSILANE AND SILICON FOR USE IN THE PRODUCTION OF TRICHLOROSILANE
    Publication number: 20130142722
    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 40 and 10.000 ppm by weight barium and optionally 40-10000 ppm by weight copper The invention further relates to silicon for use in the production of trichlorosilane by reaction of silicon with HCl gas, containing between 40 and 10.000 ppm by weight barium and optionally 40-10000 ppm by weight copper, the remaining except for normal impurities being silicon.
