Abstract
The invention discloses a preparation method for polishing diamond powder sapphire. The method is characterized by comprising the following steps: (1) choosing raw materials, wherein the raw materials adopt semi-finished polycrystalline diamond powder, and the center granularity is stabilized at 3mu m; (2) solid content, namely taking a certain amount of water, putting into an agitator to agitate, and adding the chosen diamond powder material, wherein the solid content is required to be 5%; (3) adjusting pH, namely adding a little of sodium silicate to adjust pH, so that the pH value achieves 9-10, and stirring for an hour; and (4) improving the suspension property, namely adding 0.05% of dispal, and stirring for an hour. The preparation method has the beneficial effects that the diamond powder sapphire has good cutting quantity, good smoothness on the polished surface, high safety and good suspension property.
