Introduction

Julien Claudius Marchal is an accomplished inventor based in Ann Arbor, MI (US). He holds a total of 5 patents that showcase his contributions to the field of materials science. His work primarily focuses on the development of innovative methods for producing silica and silicates.

Latest Patents

One of his latest patents is titled "Glycoxy silanes as a source of silica and silicate precipitates." This invention discloses glycoxy silanes as a source of silica, which is precipitated through advantageous chemical reactions, preferably beginning with biogenic silica. The process involves hydrolyzing alkoxy C—O—S in a controlled manner to nucleate the formation of silica nanoparticles. The growth rate of these particles is meticulously controlled, allowing for the recovery of particles with known sizes, size distributions, specific surface areas, and pore sizes.

Another significant patent is "Method of producing alkoxysilanes and precipitated silicas from biogenic silicas." This method outlines a multi-step process that begins with mixing biogenically concentrated silica with a liquid polyol, followed by heating the mixture. A base is then added to create a reaction mixture, which is filtered to remove undissolved biogenic silica. The alkoxysilane is subsequently purified through various techniques, and any residual base is neutralized to ensure the purity of the final product.
