Latest Patents

Gottanka holds a patent for a "Process for producing polycrystalline silicon granulate." This process involves the use of a fluidized bed reactor, where a fluidized bed region is maintained by a gas flow and heated by a heating apparatus. Seed particles, along with a feed gas that includes hydrogen and silane or halosilane, are continuously supplied. Elemental silicon is deposited on the seed particles, forming silicon granulate, which is discharged as a continuous product stream from the reactor. The quality and formation of the product stream are influenced by the fluidized bed temperature, which can be monitored through the temperature of an offgas stream from the fluidized bed region. This temperature is a critical variable that can be determined and controlled using a defined mass and energy balance scheme.
