Title: Jorulf Brynestad: Innovator in Superconducting Materials
Introduction
Jorulf Brynestad is a notable inventor based in Oak Ridge, TN, with a focus on superconducting materials. He holds three patents that contribute significantly to the field of materials science, particularly in the production of superconductors.
Latest Patents
Brynestad's latest patents include a method of producing lead-stabilized superconductor precursors and a method for preparing metal oxide superconductor powder precursors. The first patent describes a process where a solution of metal cations is introduced into a furnace at temperatures ranging from 600 to 1000 degrees Celsius for a duration of 0.1 to 60 seconds. This innovative process results in micron to submicron size powders without the typical loss of the lead stabilizer. The powders produced exhibit a narrow particle size distribution and small grain size, making them readily convertible to a superconducting composition upon subsequent heat treatment. The precursors can be placed in a metal body that is deformed to form a wire or tape, which is then heated to create a superconducting article. This method allows for a significant reduction in heat treatment time, facilitating the continuous processing of powders into superconducting wire, tape, or multifilamentary articles through the powder-in-tube process. His second patent focuses on the preparation of finely-divided titanium diboride or zirconium diboride powders by reacting gaseous boron trichloride with various titanium and zirconium materials.
