NANOCOMPOSITE OF CERIUM OXIDE-ALUMINOSILICATE TUBES AND PROCESS FOR THE PREPARATION THEREOF

摘要

The invention relates to chemical industry and is intended for the preparation of nanocomposite cerium oxide-aluminosilicate tubes which can be used in pharmaceutics or cosmetology. Weight part of cerium dioxide nanoparticles in the nanocomposite is from 0.5 to 30%, and size thereof within the range of 4–15 nm. A process for the nanocomposite preparation involves the preparation of aqueous suspension of aluminosilicate tubes, deposition of cerium oxide by addition of cerium nitrate solution and ammonium hydroxide solution.
