Title: The Innovations of Ernest M Jost
Introduction
Ernest M Jost is a notable inventor based in Plainville, MA (US), recognized for his significant contributions to the field of electrically conductive materials. With a total of 15 patents to his name, Jost has made remarkable advancements in the development of materials that enhance electrical conductivity.
Latest Patents
One of Jost's latest patents focuses on an electrically conductive material and the method of making it. This invention involves creating electrical contact material from intimate mixtures of silver powder and a second phase material. The second phase material is milled to achieve a specific grain distribution, with approximately 90% of the particles being less than 7-10 microns, around 50% between 2 and 5 microns, and about 10% less than 0.8 to 1.0 microns. The process includes adding the second phase material to a silver salt solution, ammonium hydroxide, and hydrazine hydrate, resulting in a precipitate of second phase material particles covered with silver. For applications requiring free-flowing particles, the material is compacted without any binder, broken into chunks, and milled to create granules. Additionally, Jost has developed homogeneously doped tin oxide particles, where tin oxide and the oxide of the dopant are dissolved in nitric acid to produce finely dispersed oxides, which are then calcined and ground to the desired grain size distribution.
Career Highlights
Throughout his career, Jost has worked with prominent companies such as Chemet Corporation and Texas Instruments Corporation. His experience in these organizations has contributed to his expertise in the field of electrical materials and innovations.
