Dependence of the Product's Phase Composition on the Ratio of Precursors in Plasmadynamic Synthesis of Silicon Carbide

In this work, the powder of nanoscale cubic SiC was obtained by the plasmodynamic synthesis in a coaxial magnetoplasma accelerator (CMPA) with a graphite central electrode and an accelerator channel. The synthesis method allows obtaining a product with a high content of nanoscale cubic silicon carbide. The work is aimed to study the influence of the precursor’s ratio on the product. The synthesized products were analyzed by X-ray diffraction and transmission electron microscopy.

Синтез нанокристаллического диборида титана в гиперскоростной плазменной струе

Results of experimental investigations of directly synthesizing nanocrystalline titanium diboride in a hypervelocity jet of electrodischarge plasma generated by a pulse high-current coaxial magnetoplasma accelerator with titanium electrodes are presented. The main result of the investigations is manufacturing a product with a mass of up to ∼3 g containing more than 90% of titanium diboride obtained mostly in the form of hexagonal and dodecagonal particles.
