Abstract
1501745 Double phosphates of barium HOECHST AG 3 Oct 1975 [3 Oct 1974] 40664/75 Heading C1A [Also in Divisions C3 and C7] Phosphates BaZn 2 (PO 4 ) 2 and where M = Co or Mg and n = 0 to 0À8 are made by precipitation from an aqueous solution of the appropriate chlorides or nitrates by addition of H 3 PO 4 and subsequent neutralization, e.g. with an alkali solution, to pH 5À8-6À0. Ba-Zn phosphate may be prepared at room temperature, and the others at 90 C. Phosphates wherein M=Mg and n=0À1, 0À2, 0À4 and 0À8 are claimed per se. The compounds, optionally with a polymeric binder, H 3 PO 4 and/or pigment, are applied to Fe or steel as anti-corrosion coatings (see Division C7).
