Cleaning baths for the removal of a coating containing niobium on a substrate, consisting of an aqueous solution of hydrogen peroxide and of alkali metal hydroxide. The coating is treated with the bath, to remove it from the substrate by dissolving.

Process for removing a coating containing niobium from a substrate

Process for inhibiting the corrosion of equipment made of titanium or of alloys containing titanium by a solution containing a peroxy compound. To effect the inhibition, a solution containing calcium, strontium or barium ions is used.

Process for inhibiting the corrosion of equipment made of titanium

Process for polymerizing in a reactor containing a polymerization mixture, and in aqueous suspension, a halogen-containing vinyl monomer, using a lipo-soluble initiator which generates free radicals, in the presence of an effective amount of an inhibitor of crust formation derived from a sulfur-containing organic compound, wherein the inhibitor of crust formation consists of anions derived from at least one arylsulfonic acid.

Process for polymerizing, in aqueous suspension, halogen-containing

A coating composition for application to an electrically conductive and relatively inert support at least the surface layer of which is titanium or a titanium alloy, to form a coated electrode for electrochemical processes, the composition essentially containing thermally decomposable compounds of iridium and of at least one non noble element selected from the group consisting of lithium, boron, beryllium, magnesium, gallium and germanium, in a liquid vehicle, the atomic ratio of iridium/non noble element being between 1/4 and 8/1. An electrode provided with a coating of this composition exhibits, inter alia, increased service life.
