Title: Gerald G Endres: Innovator in Goethite Production
Introduction
Gerald G Endres is a notable inventor based in Hastings, MN (US). He has made significant contributions to the field of materials science, particularly in the production of goethite particles. With a total of 2 patents, his work has implications for high-density magnetic recording media.
Latest Patents
Endres's latest patents focus on innovative processes for making goethite. The first patent describes a method for producing spindle-shaped goethite particles by oxidizing a ferrous carbonate intermediate in the presence of a growth modifier. This process results in goethite particles that have a narrow size distribution, high aspect ratio, and are substantially dendrite-free. These properties enhance their suitability for use in high-density magnetic recording media. The second patent outlines a method that involves reacting an alkali compound with an iron (II) salt in aqueous solution to form a precipitated complex intermediate. This method includes a controlled oxidation process to convert iron (II) to iron (III), ultimately producing goethite seed particles.
