The W-Al2O3 system is thermodynamically analyzed at T = 2400 K and P = 1 × 10−3 bar, and principal chemical reactions and their directions are determined from the sign of ΔG react. Although solid tungsten does not directly react with Al2O3 melts,

The behavior of the Mo-W-Al2O3 system at T = 2400 K and P = 1 × 10−5 bar is considered, and the main chemical reactions that implement the oxidation of Mo and W by the products of dissociative evaporation of the melt are determined. The gas-phase

We examine the behavior of the Mo-W-Al2O3 system at T = 2400 K and p = 100 Pa and identify the main chemical reactions that lead to the oxidation of Mo and W. The results indicate that, under these thermodynamic conditions, direct reaction between Mo

We examine chemical reactions that lead to the oxidation of tungsten in the W-Al2O3 system at T = 2350–2500 K and p = 1–105 Pa. The results indicate that, for p ≥ 10 Pa, tungsten oxidizes through reactions with both Al2O3 vapor and dissociation

The main chemical reactions and composition of gas and solid phases have been determined for the equimolar ratio Mo: W: O2 = 1: 1: 2 at T = 2400 K in the pressure range of 1-1 x 10-5 bar. It is established that the character of the main processes of

Gibbs free energy minimization was used to consider the formation of complex molybdenum oxide (Mo2O6) at 2400 K in the range of pressures from 1 to 1 to 1 × 10−5 bar for the basic component ratio Mo: O2 = 1: 1. Several ways are shown to lead to Mo

The W-Al2O3 system is considered at a basic component ratio of 1: 1. The composition and component concentrations in the closed system under isobaric-isothermal conditions and a residual pressure of 1 × 10−5 bar are determined by stochastic simula
