A.V.Luikov Heat and Mass Transfer Institute of the National Academy of Sciences of Belarus has developed an innovative technology of high-temperature synthesis of powders of silicon carbide and other refractory materials in reactor electrothermal fluidized bed (ETFB reactor), a distinctive feature of which is that the heating of the reacting components occurs by passing an electric current through a fluidized layer of electrically conductive carbon particles, with direct conversion of electrical energy into thermal energy at temperatures of 800 - 1900°C, which causes energy activation of reagents.
The released energy ensures the occurrence of endothermic reactions, and electric discharges between fluidized particles create a microplasma region and destroy chemical bonds in the molecules of the reacting substances. Synthesis of SiC proceeds on the surface of particles of a carbon reducing agent, on which vapors of silicon monoxide SiO are deposited, formed during the evaporation and dissociation of silica SiO2, and the interaction of its melt with carbon at a temperature above 1750 °C.
The efficiency of the technology is ensured by intensive heat and mass transfer between gas and solid particles, fluidity of the layer and its isothermality.
The ETFB reactor provides the possibility of process automation, composition uniformity and high purity of the final product.
The main characteristics of the technology:
|maximum temperature||до 1900°С|
|resulting product||β-SiC и α-SiC|
|performance||до 3 kg/h|
|high energy efficiency|
|the possibility of selective synthesis of various SiC polytypes|
The technology is widely used in areas where high temperatures and aggressive media are used: in the aerospace, chemical, nuclear industries, in microelectronics, in the manufacture of abrasive and cutting tools.
