Small-Size Nanoparticles and Nanofluids Fabrication via Plasma Arc

Abstract

The main issue with nanotechnology is the rapidly expanding fields of application, which necessitate heavy investment in research and development, and complicated devices to produce (<10nm) nanoparticles. The article describes the method of plasma arc technology designed for the production of metal nanoparticles, which is related to "Vapor phase techniques" when the material is heated to its boiling point. It is common knowledge that the homogeneity of the plasma heating zone is affected by the varying amperage of electric current in the thermal plasma column caused by fluctuations in plasma column resistance. For the manufacture of small-size nanoparticles, it's also essential to create a sizable heating zone and give the feed materials plenty of time to vaporize completely. The suggested technique uses an electric arc, powered by a constant current power source, to produce a lengthy high-temperature plasma zone.
