His work primarily focuses on the preparation and application of silica particles in various industries.

Latest Patents

Amiche's latest patents include a method for preparing hollow silica particles and a silica capable of being used in toothpaste compositions. The first patent describes a method for creating hollow particles with a dense silica shell. This is achieved by precipitating active silica from an aqueous alkaline metal silicate on a core made of a different material. The core material is then eliminated without damaging the silica shell. These hollow silica particles have diverse applications, including use as insulating materials, fillers for polymers, and as abrasives in toothpaste.

The second patent details an abrasive precipitation silica suitable for toothpaste compositions. This silica has specific characteristics, including a BET specific surface area ranging from 15 to 300 m²/g and a median particle diameter of at least 10 µm. The method for preparing this silica involves reacting an alkaline metal silicate with an acidifying agent, ensuring the pH remains constant throughout the process. The resulting silica is particularly useful in enhancing the effectiveness of toothpaste formulations.
