The main purpose of this study is to develop a high frequency induction process that is capable of producing the nanoparticle suspension, as well as the investigation into the properties of nanoparticle suspension. Also the effects of the process parameters, such as cooling temperature, vacuum pressure and inert gas on the rheology of nanoparticles are investigated. Experimental results indicate that under lower vacuum pressure, the nanoparticle suspension performs a larger rheological change and produces smaller nanoparticles, whereas under lower cooling temperature, it can produce finer ones. Besides, by adding inert gas during the process, the rheology of nanoparticle suspension would change. Furthermore, by adjusting the pH value of nanoparticle suspension below 7, its surface electric potential can also be increased and subsequently acquires smaller suspension particles. Besides, the nanoparticle suspension produced by this study has a good capability of absorbing UV light.
