Abstract

This paper describes a study to optimise the yield and to control the particle size distributions of a plasma torch. SEM analysis and impactor measurements of the produced material reveal agglomeration of primary particles with aerodynamic diameter 50 nm < d < 100 nm. Tests were carried out with a DC plasma spray unit at an input power of 40 kW. Tin particles smaller than 90 micron with an oxidised surface were fed directly into the hot plasma gas zone. An augmentation of the residence time in the hot zone was achieved with a vaporisation chamber connected to a plasma torch at the flame exit.
