Production of Tungsten Spherical Microparticles in Ultrasonic Field at Presence an Activator

Abstract

It has been shown by experiments, that spherical tungsten microparticlein etching solution under the ultrasonic exposure is possible. The process of obtaining consists of two stages. At the first stage, by centrifuging a suspension of tungsten powder with an average particle size of 0.5 microns in the activator – etching from a water solution of potassium hydroxide and potassium ferricyanide, obtained tungsten thin plate of any shape, thickness 1–3 micrometers. In the second phase, in the environment of activator on a particle with an average size of 20 micron by the ultrasound laminated flat particles obtained at the first stage. Due to the ultrasound treatment in a form produced particles is close to spherical. The average particle size of the resulting powder was 42.9 micron.
