Patent ID: 7850790

Claim:
A method of making a reactive gas product comprising the steps of: a) exposing an internal metal surface of a container to a first fluid composition, comprising a silicon-containing compound for a time sufficient to allow at least some of the silicon-containing compound to react with an oxygen-containing compound present to form a silicon-treated surface on at least some of the internal metal surface, the silicon-containing compound selected from the group consisting of compounds within the general formula: SiR 1 R 2 R 3 R 4 wherein R 1 , R 2 , R 3 , and R 4 are the same or different and are independently selected from the group consisting of hydrogen, halogen, alkyl, aryl, amine, halogenated alkyl, and halogenated aryl; b) evacuating the container for a time sufficient to remove substantially all silicon-containing compound that has not reacted with the oxygen-containing compound to form the silicon-treated surface; c) exposing the silicon-treated surface to a second fluid composition, the second fluid composition comprising a reactive gas having a concentration that is at least 10 times greater than the intended reactive gas concentration of the reactive gas product; d) evacuating the container for a time sufficient to remove substantially all of the second fluid composition, thus forming a passivated internal metal surface in the container including the silicon treated surface and reactive gas adsorbed on the silicon treated surface; and e) filling the container with a third fluid composition having the intended reactive gas concentration for the reactive gas product.
