摘　　要：针对可用于冷烧结的中间液相十分有限的问题,利用氯化胆碱/丙二酸制备的低共熔溶剂作为中间液相,在不同压力和温度下,对CuO陶瓷粉体进行了冷烧结。结果表明:在400℃,540 MPa,w(低共熔溶剂)=10%的条件下,可获得相对密度为88.2%的CuO陶瓷。加入低共熔溶剂可以使CuO的相对密度相较于干压后提升19.4%,低共熔溶剂可以作为冷烧结CuO的中间液相。The available intermediate liquid phase during cold sintering were very limited.In this paper,deep eutectic solvent prepared by choline chloride and malonic acid was used as an intermediate liquid phase during cold sintering of CuO at different pressures and temperatures.The results show that CuO with a relative density of 88.2%is obtained by adding w(deep eutectic solvent)=10%at 400℃and 540 MPa.The relative density of CuO is increased by 19.4%after cold sintering compared to dry pressed.Deep eutectic solvent can be used as an intermediate liquid phase during cold sintering of CuO.
