ABSTRACT OF THE INVENTION There is disclosed an agent and a method for producing the same for removing impurities from a molten metal comprising a first compound capable of reacting with and removing the impurities contained in the molten metal and a second compound coated on the first compound to form a composite. The second compound has a contact angle with the molten metal less than that of the first compound, there- by causing the composite to be more wettable in the molten metal as compared to the first compound. This allows the composite to penetrate into the molten metal, resulting in the first compound efficiently reacting with the impurity contained within the molten metal.
