Abstract
The paper proposes the miscrosphere electro-plasma technology based on the processing of bottom ash generated by the Belovo Power Plant, Kemerovo region, Russia. During the electro-plasma processing, the current-voltage characteristic of plasma flow is determined. It is shown that it considerably depends on the gas rate. For example, at 300 А arc current and the increase of gas rate from 1.0 to 2.0 g/s, the arc voltage grows from 130 to 180 V. The X-ray photoelectron spectroscopy allows obtaining the distribution maps for the elemental composition of the microsphere surface and detecting the element concentration. From the infrared spectroscopy, it is possible to conclude that the amorphized layer of obtained microspheres is characterized by an ordered structure, because 1093.82 сm-1 maximum position of the absorption band for stretching vibration is as close as possible to that for silica glass (1100 сm-1) representing a more ordered polymer structure.
