PROCEDE D'OBTENTION D'UN LIANT PHOSPHATIQUE D'ALUMINIUM ET CHROME

The process comprises reaction of phosphoric acid with hydrated alumina and chronic anhydride. The hexavalent chromium is reduced to trivalent chromium using formic aldehyde. The resulting refractory binder increases corrosion resistance and service life.
