OXIDE SHELL FORMATION ON INORGANIC SUBSTRATE VIA OXIDATIVE POLYOXOANION SALT DEPOSITION |
摘要 |
The present invention provides a process for depositing an oxide coating on an inorganic substrate, including providing an aqueous composition containing a tetraalkylammonium polyoxoanion and hydrogen peroxide; contacting the aqueous composition with an inorganic substrate for a time sufficient to deposit a hydroxide derived from the polyoxoanion on surfaces of the inorganic substrate to form an initially coated inorganic substrate; and heating the initially coated inorganic substrate for a time sufficient to convert the hydroxide to an oxide to form on the inorganic substrate an oxide coating derived from the polyoxoanion. The inorganic substrate may be a ceramic material or a semiconductor material, a glass or other dielectric material, and the ceramic material may be a lithium ion battery cathode material. |
