  • Patent number: 10066128
    Abstract: The present disclosure provides a method for preparing an aluminum oxide polishing solution. The methods include: 1) mixing a silane coupling agent, ethyl alcohol, and water to form a hydrolysate; 2) under a condition of heating and stirring at a temperature between 95° C. and 110° C., adding the hydrolysate into aluminum oxide powder; keeping stirring while heating till liquid is completely volatilized, thereby obtaining a modified aluminum oxide; 3) grinding the modified aluminum oxide into powder and dispersing the powder into water; adjusting solution pH to 9.5-10.5, thereby obtaining the aluminum oxide polishing solution. It may achieve a polishing efficiency of pH=13.00 by using the aluminum oxide polishing solution of the present disclosure; meanwhile, less scratches will occur to a polishing disc.
