Silicon Wafer Production

In this process, MG-Si is first ground in a ball-mill to produce very fine (75% 40 M) particles which are then fed to a Fluidized Bed Reactor (FBR). There the MG-Si reacts with anhydrous hydrochloric acid gas (HCl), at 575 K (approx. 300C) according to the reaction: Si + 3HCl → SiHCl 3 + H 2. The hydrochlorination reaction in the FBR
