Definitions
- Example 4 Using the same manganese dioxide powder as in Example 1, the manganese dioxide powder is dispersed in pure water so that the slurry concentration becomes 10 wt%, and potassium hydroxide is added to adjust the pH to 11.9. A manganese dioxide slurry having a potential value of 0.561 V was prepared. And the grinding
- Comparative Example 1 For comparison, a polishing test similar to that of Example 1 was performed using commercially available colloidal silica (manufactured by Fujimi Incorporated, Compol 80, average particle size: 70 nm to 80 nm). This colloidal silica was dispersed in pure water so as to have a slurry concentration of 10 wt% to prepare a colloidal silica slurry. And the grinding
- the dimanganese trioxide slurry of Comparative Example 2 had a pH of 5.9 and an oxidation-reduction potential value of 0.604V. Using this slurry, a polishing test was conducted under the same conditions as in Example 1 to investigate the polishing rate. The results are shown in Table 1.
- Comparative Example 3 In Comparative Example 3, manganese dioxide powder (average particle size 0.5 ⁇ m) obtained in the same manner as in Example 1 was dispersed in water to form a slurry, and hydrochloric acid was added to this slurry to adjust the pH to 4.5. It was.
- the manganese dioxide slurry of Comparative Example 3 had a redox potential value of 0.900V.
- the oxidation-reduction potential values V and pH are based on the phase equilibrium diagram (potential-pH diagram) showing the oxidation-reduction reaction of manganese (Mn) shown in FIG. 1, and the particles in the slurry are manganese dioxide.
- the oxidation-reduction potential value and pH of Comparative Example 3 satisfy the expression 1.014 ⁇ 0.0591 pH ⁇ V ⁇ 1.620 ⁇ 0.0743 pH according to the relational expression of V and pH, but the pH is pH 6. It is a value lower than 5.
- the polishing test results of Comparative Example 3 are shown in Table 1.
- FIG. 2 shows the results of measuring the surface roughness of the polished surface of the substrate after the polishing test in Example 1 using an AFM (Atomic Force Microscope: Nanoscope IIIa manufactured by Veeco).
