Title: Bruno Ceccaroli: Innovator in Isotope Separation and Silicon Purification
Introduction
Bruno Ceccaroli is a notable inventor based in Kristiansand, Norway. He has made significant contributions to the fields of isotope separation and silicon purification, holding a total of 3 patents. His innovative methods have the potential to impact various industries, particularly in materials science and semiconductor manufacturing.
Latest Patents
One of Ceccaroli's latest patents is a method for the separation of isotopes. This invention focuses on obtaining isotopically pure fractions by separating natural isotope mixtures in elements. The method employs hydrogen as a ligand on the elements to be isotopically separated, resulting in gaseous compounds at practical temperatures and pressures. Specifically, it details a process for obtaining isotopically pure 28SiH4 on an industrial scale using a chromatographic column.
Another significant patent is related to the refining of metallurgical grade silicon. This invention describes a purification method where a calcium-containing compound is added to molten silicon before or after it is tapped from the furnace. The silicon is then cast and solidified at a high cooling rate, followed by a two-step leaching process to enhance purity. The first step involves treating the silicon with an aqueous solution of FeCl or FeCl and HCl, while the second step uses an aqueous solution of HF or HF/HNO.
