    Abstract: Provided is a method for preparing a mixture abrasive slurry for CMP (chemical mechanical polishing) to improve polishing selectivity and to lower RMS surface roughness. A method comprises the steps of (S10, S20) mixing a BaCO3 powder and a TiO2 powder in a ratio of 1:1 with deionized water; (S30) milling the obtained one by using a zirconia ball and (S40) drying it; (S50) molding the dried one in a mold at a pressure of 6,000 kgf/cm^2; (S60, S70) sintering the molded one to prepare a BTO (BaTiO3) target; and (S80) pulverizing the BTO target to prepare a BTO abrasive and (S90) mixing the BTO abrasive with a slurry raw solution.
