Phase composition reproportioning of the plasma dynamic synthesis product of the zinc-bismuth-oxygen system

Abstract

This article shows the possibility of obtaining nanosized materials based on zinc oxide and bismuth oxide by plasma dynamic synthesis. The main research in the article is the results on the influence of the precursors mass on the products phase composition of the Zn-Bi-O system. X-ray phase analysis allowed to establish the possibility of zinc oxide and bismuth oxide synthesis in one short cycle of the coaxial magnetoplasma accelerator. Changing the metal bismuth batch weight allows to adjust the bismuth oxide content in the final product. Transmission electron microscopy confirms the presence of zinc oxide phases in the bismuth oxide shell in the obtained material. Evaluation of the bismuth oxide shell thickness by determining the average size of the coherent scattering region showed that it is 30 nm.
