Abstract:
An article comprising a thermally associated nondeleterious contaminated polycrystalline metal oxide coated three dimensional particle substrate produced by the process comprising: contacting said particle substrate which include external surfaces and shielded surfaces which are at least partially shielded by other portions of said substrate with a composition comprising a metal oxide forming compound to form a reactant mixture, contacting said mixture at fast reaction oxidizing and elevated temperature conditions in a reaction zone in the presence of an oxidizing agent effective to form a metal oxide coating on at least a portion of the surfaces of said three dimensional substrate including at least a portion of the shielded surfaces of said particles at said conditions and without substantially adversely effecting the solid integrity of the substrate; said fast reaction oxidizing conditions in said zone including an average particle residence time of less than one second when at fast reaction oxidizing elevated temperature conditions.
