Process development of a novel arc spray nanoparticle synthesis system (ASNSS) for preparation of a TiO₂ nanoparticle suspension

This article presents the development of an innovative technology to manufacture TiO₂ nanoparticles. Manufacturing nanoparticles is considered as a crucial step towards product and process innovation. In our proposed process, a titanium rod. as the electrode, is melted and vaporised in deionised water, which is used as an insulating liquid. The vaporised metal particles are then rapidly quenched by the designed cooling system, and thus nanocrystalline powders are nucleated and formed. By implementing the system, we have successfully developed the processing equipment of the arc spray nanoparticle synthesis system (ASNSS). The experimental results indicate that uniformly distributed and well-controlled TiO₂ nanoparticle size can be manufactured by ASNSS.
