*the impurity composition was determined by the GDMS method (glow discharge mass spectrometry).
** the phase composition of the synthesized product was determined by X-ray diffractometry.
The complex of technological equipment developed by BRC Spectr allows the synthesis of polycrystalline silicon carbide from high-purity quartz and high-purity carbon (graphite). The equipment includes plants for the production of quartz, for the production of graphite, for the synthesis of powder and for its subsequent annealing (removal of excess carbon).
The machine is designed for obtaining high-purity fractions of silicon dioxide SiO2 purity up to 99,9995 %. High-purity quartz is used for the production of materials and products for
High-quality raw materials for the synthesis of silicon carbide single crystals of modifications 4H-SIC and 6H-SIC used in electronic devices.
The plant is designed for growing bulk silicon carbide single crystals by sublimation (LETI method). This plant can grow crystals from 4 to 6 inches. The sublimation method is
