REC Silicon's fluidized bed reactor (FBR) process

With the Fluidized Bed Reactor process, REC Silicon has taken a major step forward in silicon purification using less energy. Instead of using seed rods, FBR uses seed granules of purified silicon. The seed granules are fed into a chamber that has heated silane gas entering from below and exiting above.
