这项工作使用在水溶液中通过盐碱反应制备的 CuO 纳米颗粒进行金属-金属键合。通过混合 Cu(NO3)2 水溶液和 NaOH 水溶液制备 CuO 纳米粒子的胶体溶液。尽管也获得了 Cu2(OH)3NO3,但在 Na/Cu 比例为 1·7、温度为 20°C 时,生成了由 CuO 纳米粒子组成的亚微米大小的叶状聚集体。老化过程是由在 20°C 下制备颗粒然后在 80°C 下老化组成的过程,提供了从 Cu2(OH)3NO3 到 CuO 的转变,而不会损坏叶子结构。在400℃的氢气中,使用颗粒作为填料粘合分离盘所需的剪切强度对于在Na/Cu比为1·7的条件下通过老化过程制备的颗粒来说最大为32·5MPa。这些结果表明,高纯度 CuO 颗粒的叶状聚集体的形成导致了有效的金属-金属键合。
This work performs metal–metal bonding using CuO nanoparticles prepared with salt base reaction in aqueous solution. A colloid solution of CuO nanoparticles was prepared by mixing Cu(NO3)2 aqueous solution and NaOH aqueous solution. Submicrometre sized leaf-like aggregates composed of CuO nanoparticles were produced at a Na/Cu ratio of 1·7 and at 20°C, though Cu2(OH)3NO3 was also obtained. An aging process, which is a process composed of preparation of the particles at 20°C and then aging them at 80°C, provided transformation from Cu2(OH)3NO3 to CuO with no damage of the leaf structure. The shear strength, which was required for separating discs bonded using the particles as a filler at 400°C in H2 gas, was 32·5 MPa at the maximum for the particles prepared at the Na/Cu ratio of 1·7 with the aging process. These results indicated that the formation of leaf-like aggregates of CuO particles with high purity led to efficient metal–metal bonding.
