Title: Innovations of John R Peterson
Introduction
John R Peterson is a notable inventor based in Salem, OR (US), recognized for his contributions to the field of materials science. He holds a total of 7 patents, showcasing his innovative approach to refining niobium and related materials.
Latest Patents
One of his latest patents is focused on the electron-beam melt refining of ferroniobium. In this process, niobium (Nb) is refined from FeNb by utilizing electron beam melt refining techniques. The method involves determining the amount of impurities in the FeNb that form suboxides with oxygen. Sufficient oxygen is added to create 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 recovery. Additionally, the oxygen can be introduced as an oxygen-containing compound, such as Nb₂O₅. The purified niobium can undergo further electron beam melt refining cycles to achieve the desired purity.
Another significant patent involves the recovery of niobium metal. In this process, ferroniobium, ferrotantalum, and ferrovanadium alloys are hydrogenated to facilitate crushing. They are then nitrided and acid-leached to produce a soluble iron nitride leachate and a niobium, tantalum, or vanadium nitride residue. This residue can be denitrided to yield the metal, which can subsequently be recovered through melting.
