Abstract
The processes of synthesis of silicon carbide from natural mineral raw materials - diatomite mixed with coke (or coal, or graphite) have been studied. High-temperature heating was carried out using a flow of concentrated solar radiation (CSI) of high density (200 W/cm 2 ). The mixture was placed in a graphite crucible mounted on the focal zone of the Large Solar Furnace. The crucible with the material sample after irradiation with the XI flow was cooled in an arbitrary manner for 30 minutes. The analysis showed that such a diffraction pattern is due to the presence of three phases - silicon carbide β- SiC with a cubic system with lattice parameters a = 4.36 A and α- SiC with a hexagonal lattice with parameters a = 3.07 A c = 15.11 A, as well as graphite C of the hexagonal system.
