Analysis of phase composition of materials synthesized in carbon and tungsten trioxide pyrolysis in a DC electric arc in helium medium

Abstract

The paper presents phase analysis of materials synthesized as a result of composite electrode (WO3-C) pyrolysis in a dc electric arc in helium medium. Qualitative x-ray phase analysis is performed. Radiograms of crystal lattices of nanoparticles present in the materials were obtained using high-resolution transmission electron microscopy. Nanocrystals were identified by crystal lattice images. Statistical analysis of phase compositions of the materials is carried out. Mean values and variances of the relative content of nanocrystals of different chemical and phase compounds in crystal structures of the synthesized materials are determined.
