Плазмодинамический синтез оксидов вольфрама в среде углекислого газа

Abstract

In the present study, we synthesized utrafine tungsten oxide predominantly containing cubic phase (> 90 wt. %) when spraying the high-speed plasma jet in the carbon dioxide medium. Interaction between high-energy plasma and CO2 medium results in releasing oxygen, which oxidizes tungsten-containing plasma generated by a coaxial magnetoplasma accelerator. The mentioned process provides the formation of ultrafine tungsten oxide powder. X-ray diffractometry analysis allowed determining the dominance of cubic phase in the product structure. The revealed feature of the obtained powder gives a ground to consider the plasma dynamic synthesis as a promising technique for further investigations in W-O system
