THERMODYNAMIC SIMULATION OF THE BEHAVIOR OF A CARBONIZED PERICLASE REFRACTORY WITH AN ALUMINUM-BASED ANTIOXIDANT

摘要

Using the method of Gibbs energy minimization, a computer-aided thermodynamic simulation of phase and chemical transformations in the MgO - C - Al - H_2O - air system at 298-2400 K is carried out to describe the behavior of a carbonized periclase material with an Al- based anti oxidizing additive. The effect of temperature and environmental atmosphere on phase and chemical transformations in the material bulk and material's pore space is studied. The properties of a carbon matrix doped with aluminum are discussed.
