Design of micro-jet plasma system: a novel nanoparticles manufacturing method in atmospheric pressure

Micro jet atmospheric (MPJ) plasma was first utilized to create nano-sized crystals. Nanosized particles may have advantageous characteristics such as better internal quality and dissolving rates of the product compared to traditional crystalline goods. A nebulizer system sprays an aerosol solution into plasma by use of a carrier gas in a cold plasma crystal (argon). The plasma warms and loads the droplets causing solvent and columbic fission evaporation, and then the nucleation and crystal formation start within the limited volume given by the tiny drops. This produces nano-sized crystals. MPJ was used to establish the operating parameters for producing nano-sized ZnSe material crystals using electron microscope transmitting and X-ray powder diffraction tests as well as sensitivity testing have been carried out. Sensitivity tests showed lower friction sensitivity for the nano-scale product, suggesting a better internal quality of the crystal product.
