Title: Wolfgang Stoiber: Innovator in Silicon Production
Introduction
Wolfgang Stoiber is a notable inventor based in Eggenfelden, Germany. He has made significant contributions to the field of silicon production, holding 2 patents that showcase his innovative approaches to enhancing safety and efficiency in the industry.
Latest Patents
One of his latest patents is a process for producing polycrystalline silicon. This invention involves the installation of a shield around a Siemens reactor prior to harvesting polysilicon rods. This shield allows the upper, bell jar-like shell to be removed for cleaning while protecting the polysilicon rods from contamination and increasing the safety of nearby personnel. The polysilicon rods are harvested while the shield is present, ensuring a cleaner and safer working environment. Another significant patent is a method for processing an etching mixture formed during the production of highly pure silicon. This method recovers acid from an aqueous etching mixture containing HF, HNO, HSiF, and HNO. The used etching mixture is distilled progressively, allowing for the recovery of dilute acid containing more than 90 wt. % of silicon dissolved as hexafluorosilicic acid in the first fraction. The water content is reduced, and the mixture is concentrated by evaporation, resulting in a residue that is disposed of properly.
