Abstract:
At this stage of the development of industrial nanostructure compounds, materials containing carbides and borides of metals, especially zirconium ZrB2/ZrC, are widely used composite materials of nanostructures.
The purpose of the work is to study the physical and chemical bases of high-temperature carbide production processes and borides of the specified system, which will give a chance to perform a minimum number of experiments.
A full thermodynamic analysis (FTA) of the interaction of ZrO2 and B2O3 with carbon under a vacuum (0.0001 atm.) has been conducted.
The initial content of the components correspond properly to the stoichiometry of the following reactions:
ZrO2 + B2O3 + 5C = ZrB2 + 5СО (1)
2ZrO2 + B2O3 + 8C = ZrB2 + ZrC + 7СО (2)
The main results of this research are presented as FTA diagrams (dependence of the content of components on temperature in the range of 700-1600 K).
Based on the results of the provided analyses, an experimental research on the production of composite materials was carried out.
