| titleOfInvention | Polishing composition and method of manufacturing magnetic disk substrate |
| abstract | The present invention provides a polishing composition capable of effectively reducing the number of scratches present on a surface after polishing while maintaining a high polishing rate. A polishing composition for use in polishing a magnetic disk substrate is provided. The polishing composition contains abrasive grains, an acid, an oxidizing agent and water. The abrasive grains contain at least silica particles. The average primary particle diameter of the abrasive grains measured by the BET method is 1 nm or more and 50 nm or less. The pH is 1.8 to 3.0. The amount of sodium hydroxide required to raise the pH to 1.0 is 0.03 mol / L or more and 0.2 mol / L or less. 【Selection chart】 None |
