摘要: We successfully developed a new type of micromixer for instant mixing and rapid heating under high pressure temperature. The mixer has several distinguished features: the within ten milliseconds, good insulation heat, throughput. confirmed these features by examination experiments. Finally, we tried to produce bohmite nanoparticles super critical water reaction at 400°C in 30 MPa, fine particles average diameter which is ca. 20 nm were obtained. It expected that will be applied widely various reactions require severe conditions.
