Title: Innovations by Yuri L Pozdeev-Freeman
Introduction
Yuri L Pozdeev-Freeman is a notable inventor based in Kennebunk, ME (US). He has made significant contributions to the field of capacitor technology, holding a total of five patents. His work focuses on enhancing the performance and reliability of tantalum and niobium capacitors.
Latest Patents
Among his latest patents are two innovative methods related to sintered tantalum and niobium capacitor pellets doped with nitrogen. The first patent describes a pellet for use in electrolytic capacitors, which is comprised of a powder selected from either tantalum or niobium. This pellet is characterized by its porosity, absence of oxygen, and nitrogen diffusion, all achieved in an oxygen-free environment. The production method involves pressing the powder into a self-contained pellet, removing oxygen, annealing the pellet, and subjecting it to nitrogen gas to enhance its properties.
The second patent outlines a method for doping sintered tantalum and niobium pellets with nitrogen. This method ensures that the resulting pellets are substantially free of nitride precipitate on their outer surfaces. The process includes heating the pellets in a nitrogen gas atmosphere and then in a vacuum, allowing nitrogen to diffuse into the inner portion of the pellet, thereby improving DCL stability and reliability compared to previous nitrogen-doped versions.
