The Gas Institute of National Academy of Science of Ukraine developed the facility for pyrocarbon application on the particles of quartz sand through methane pyrolysis in reactor with electrothermal fluidized bed. Thickness of the bed of pure pyrolytic carbon can be controlled within set limits, depending on the temperature, fluid dynamics and duration of the process. The formation of different types of microdischarge plasma takes place at different temperatures. Microdischarge plasma increases the temperature of the individual particles for a very short time, influencing the chemical reaction and the phase transitions passing. Quartz sand encapsulated by pyrocarbon is then used for the carbothermic reduction in order to obtain high-purity silicon.References
