Abstract:
1. A process for removing a substance from at least a portion of the surface of a reaction chamber, said process comprising: providing a reactor chamber wherein at least a portion of the surface is at least partially coated with the substance and wherein the substance has a dielectric constant of 4.1 or greater and is at least one member of the group consisting of a transition metal oxide, a transition metal silicate, a Group 13 metal oxide, a Group 13 metal silicate, a nitrogen containing transition metal oxide, a nitrogen containing transition metal silicate, or a laminate comprising at least one layer of the group consisting of a transition metal oxide, a transition metal silicate, a Group 13 metal oxide, a Group 13 metal silicate, a nitrogen containing Group 13 metal oxide, a nitrogen containing Group 13 metal silicate, a nitrogen containing transition metal oxide, a nitrogen containing transition metal silicate; introducing a reactive agent into the reaction chamber wherein the reactive agent comprises at least one fluoride containing compound and at least one other compound comprising BCl exposing the reactive agent to one or more energy sources sufficient to react the substance with the reactive agent and form a volatile product; and removing the volatile product from the reaction chamber.
