Latest Patents

Richard S. Puopolo holds a patent for the "Electron-beam melt refining of ferroniobium." This patent describes a method for refining niobium (Nb) from ferroniobium (FeNb) using electron beam melt refining. The process involves determining the amount of impurities in FeNb that form suboxides with oxygen. Sufficient oxygen is added to form oxides with these impurities. The electron beam melt refining is conducted at high temperatures and low vacuum conditions, allowing for the removal of impurities as oxides from the liquid niobium, resulting in purified niobium. The oxygen is preferably added as an oxygen-containing compound, such as Nb₂O₅. The purified niobium can undergo additional refining cycles to achieve the desired purity.
