This report proffers the thorough economics of Polysilicon production via fluidized bed. The production of polysilicon from trichlorosilane and hydrogen gas is primarily conducted using the Siemens process, a method known for yielding high-purity silicon. In this process, trichlorosilane is introduced into a reactor containing heated silicon rods, where it decomposes at temperatures between 900 to 1100 degrees Celsius. The silicon from the trichlorosilane deposits on these rods, gradually building up layers of pure silicon. Simultaneously, hydrogen gas aids in the decomposition and helps control the reaction environment.
