Introduction

Lawrence B Welsh is a notable inventor based in Evanston, IL (US), recognized for his contributions to the field of materials science. He holds a total of seven patents, showcasing his innovative approach to developing advanced materials and processes.

Latest Patents

One of his latest patents is for the preparation of silicon nitride powder. This process involves subjecting a composite, which includes a monolayer of a carbonaceous pyropolymer on a silica support, to nitrogen-containing atmospheres under nitriding conditions. This method effectively forms silicon nitride, which has various applications in ceramics and electronics.

Another significant patent by Welsh is for the production of high surface area catalyst supports. This process allows for the creation of refractory materials that replicate the internal pore structure and dimensions of high surface area microporous substrate materials. By uniformly depositing a carbide-forming metal or metalloid on the internal surfaces of a carbon-donor substrate, Welsh's method achieves a balance between the diffusion rate and decomposition rate of the metal or metalloid-containing compound, resulting in a uniform deposition.
