A process for preparing trichlorosilane by reducing tetrachlorosilane in a fluidized bed reactor has the following steps: a) establishing in the reactor, a fluidized bed of silicon particles; b) heating the silicon particles to a temperature of 300°C to 1100°C by directing microwave radiation into the reactor; c) passing a reaction gas containing tetrachlorosilane and hydrogen through the fluidized bed and reacting the reaction gas with the silicon particles, to form a product gas which contains trichlorosilane and d) removing the product gas from the reactor.
