Title: Innovative Contributions of Kenneth W French in Ceramic Engineering

Introduction

Kenneth W French, an accomplished inventor based in Merrimack, NH, has made significant contributions to the field of ceramic engineering. With a total of six patents to his name, his work focuses on enhancing the manufacturing processes of ceramic materials, particularly in the creation of large cross-sectional parts.

Latest Patents

Among his latest patents, Kenneth developed a Method of Making Large Cross Section Injection Molded or Slip Cast. This innovative method outlines a procedure for producing crack-free ceramic components with substantial cross-sections. The process involves an initial mixture of ceramic powder, a binder, and a controlled amount of whiskers or fibers made from carbon, graphite, or high-temperature organic polymers. The mixture undergoes injection molding or slip casting to form a shaped article, which is then subjected to a two-step heating process in nitrogen and air atmospheres to remove the binder effectively. Finally, the shaped article is encapsulated in glass and densified through hot isostatic pressing, achieving a remarkable density of approximately 99% of its theoretical value.

Another notable patent is the Method for Fabricating Large Cross Section Injection Molded Ceramic, which elaborates on producing high-density silicon nitride using an injection molding process. This method emphasizes a controlled starting powder, a novel binder removal technique, and a prefiring step followed by isopressing and traditional sintering, allowing for the fabrication of large, high-density ceramic components.
