    摘要： An aqueous solution containing 30 ppm or more of carbon dioxide is brought into contact with a steel-making slag to elute phosphorus and calcium contained in the steel-making slag into the aqueous solution. Subsequently, carbon dioxide is removed from the aqueous solution to precipitate a mixture comprising a phosphorus compound and a calcium compound. In this manner, a mixture comprising a phosphorus compound and a calcium compound and containing phosphorus in an amount of 1% by mass or more in terms of phosphorus atom content can be produced.

    摘要： A chemically converted steel sheet having a chemically converted coating film is made by coating a Zn-based plated steel sheet with a chemical conversion treatment solution and drying the same. The chemically converted coating film is constituted by a first chemically converted layer including V, Mo, and P, and a second chemically converted layer provided on said layer and including a group 4A metal oxygen acid salt, and the ratio of pentavalent V to all the Vs in the chemically converted coating film is 0.7 or greater. The chemical conversion treatment solution includes specific proportions of V, Mo, an amine, the group 4A metal oxygen acid salt, and P, and substantially does not include hydrophilic resins, fluorine, or silicon.

    摘要： Provided is a method for obtaining a chemical conversion coating-treated zinc-aluminum-magnesium alloy-plated steel sheet having extremely excellent in corrosion resistance and adhesiveness to a resin coating film. The method is for treating the surface of a zinc-aluminum-magnesium alloy-plated steel sheet with a metal surface treatment agent, in which the metal surface treatment agent contains a compound (A) having a zirconyl ([Zr=O] 2+ ) structure, a vanadium compound (B), a titanium fluorocomplex compound (C), an organic phosphorus compound (Da) containing a phosphoric acid group and/or a phosphonic acid group, an inorganic phosphorus compound (Db), a specific aqueous acrylic resin (E), and an oxazoline group-containing polymer (F) as a curing agent, each in a predetermined amount, and the pH of the metal surface treatment agent is 3 to 6.
