摘　　要：以纳米α-Al_2O_3为原料,用乳化分散法制备出了分散性、稳定性良好的 Al_2O_3陶瓷墨水,研究了墨水的理化性能。结果表明,Al_2O_3墨水稳定性随分散剂 EFKA-4300加入量增加而增大,在2.5Vol%Al_2O_3墨水中,EFKA-4300的最佳加入量为6wt%;墨水的粘度随Al_2O_3体积份的增加而增大。打印实验证明乳化分散法制备的 Al_2O_3陶瓷墨水能够满足喷墨打印的要求。Preparation and physicochemical properties of Al_2O_3 ceramic inks based on α-Al_2O_3 was studied in the form of alumina suspension prepared and surface tensions by high-shear dispersing emulsifier.The results showed that the lowest sediment volume coincided with the lowest viscosity and occurred when 6wt% of dispersant based on the ceramic was added to the ceramic ink containing 2.5Vol% alumina.The viscosity of inks increased with solid content increasing.The ceramic inks satisfied the requirements of ink-...
