HOLLOW ALUMINOSILICATE PARTICLES AND METHOD OF MANUFACTURING THE SAME

WIPO Patent Application WO/2017/200169

A1

Disclosed are hollow aluminosilicate particles and a method of manufacturing the same. The method includes reacting a template core including an organic polymer in micelle or reverse micelle form with a silane compound and an aluminum precursor to synthesize core-shell particles having an aluminosilicate shell, which are then reacted with a basic or acidic aqueous solution, thus simultaneously forming fine pores in the shell and removing the core, thereby producing hollow aluminosilicate particles, and performing a hydrothermal reaction so as to increase the density of the hollow aluminosilicate particles. This method enables the formation of a uniform shell even without additional core surface treatment by forming negative charges during the preparation of a complex oxide through the reaction of an aluminum precursor and a silica precursor upon forming a shell, resulting in hollow particles wherein the shell is not broken during the high-density reaction but is uniform.
