Abstract
The invention provides a preparation method of nanometer ceramic powder dispersion liquid, comprising the steps of: firstly, dissolving Al2O3 in deionized water, and then instilling a dispersant to prepare a mixed liquid; instilling ammonia water to the mixed liquid to ensure that the pH value of the mixed liquid is 8-9; and carrying out ultrasonic treatment. The nanometer ceramic powder dispersion liquid prepared by using the preparation method comprises the deionized water, Al2O3 and the dispersant, wherein Al2O3 is instilled into the deionized water and then the dispersant is instilled to prepare the mixed liquid; and in the mixed liquid, 5-15g of Al2O3 is dissolved in each 100ml of deionized water and the amount of the instilled dispersant is 1.2-2.4ml. According to the preparation method, the dispersing stability is good, the nanometer ceramic powder dispersion liquid is even and stable, the properties are excellent and relatively good use reliability is provided.
