  • POLISHING LIQUID AND METHOD FOR PRODUCING POLISHED ARTICLE
    Publication number: 20200332163
    Abstract: A polishing liquid contains permanganate ions, a weak acid, and a soluble salt of the weak acid. The polishing liquid preferably has a pH of 0.5 to 6.0 at 25° C. before commencement of polishing. When a 0.1 mol/L aqueous solution of sodium hydroxide is added to 100 mL of the polishing liquid having been adjusted to pH 3.0 to 4.0 at 25° C., the amount of the sodium hydroxide aqueous solution necessary to raise the pH of the polishing liquid by 0.5 is preferably 0.1 to 100 mL. The weak acid is preferably acetic acid.
