Abstract

The calculation of Gibbs energy for reactions of interaction of ZrO2, Al2O3, SiO2, TiO2, CaO and MnO with carbon and carbon monoxide in temperature range 1273 – 2273 К (1000 – 2000 ?С) is made to select eutectic additive for structural ceramics in Al2O3–ZrO2–eutectic additive–carbon nanotube system. Considering the multi-component structure of the ceramic matrix composite in the system Al2O3–ZrO2–eutectic additive–carbon nanotube system, it is necessary to consider the process of possible carbidization, worsening the strength characteristics of the synthesized material. As a result of the analysis, it was found that eutectic additives containing Al2O3, SiO2, TiO2, CaO.
