Supercritical hydrothermal synthesis system (MOMI-cho mini)Lab-scale apparatus
This system synthesizes nanoparticles in supercritical water. The metal salt solution at room temperature is mixed with supercritical water and heated rapidly. Then the metal oxide nano particles are produced by hydrolysis of metal ion. When an organic compound as modifier is introduced into this system, the surface of the nano particles can be organic-modified. If you already have particles which should be organic modified, the particles can be feeded by slurry pump into the reactor of MOMI-cho system
Characteristics
- Highly crystallized nanoparticles can be synthesized
- Testing with various modifiers is possible.
- Continuous and fast synthesis.
- Sampling is possible while changing the experimental conditions.
