纳米陶瓷粉分散液的制备方法及纳米陶瓷粉分散液
摘要：
本发明提供了一种纳米陶瓷粉分散液的制备方法，先将Al2O3溶于去离子水中，然后滴入分散剂制成混合液，然后再向混合液中滴入氨水使混合液的pH值为8~9，然后再进行超声波处理；采用上述方法制备的纳米陶瓷粉分散液，包括去离子水、Al2O3和分散剂，将Al2O3溶于去离子水中，然后滴入分散剂制成混合液，所述混合液中每100ml去离子水中溶入Al2O3的量为5-15g、滴入分散剂的量为1.2~2.4ml。本发明分散稳定性好，纳米陶瓷粉分散液均匀稳定、各项性能优良、具有较好的使用可靠性。
摘要（英）：

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.
