According to DSC-measures (differential scanning calorimetry) of warm capacities we study the thermodynamic properties of Tl-species, produced with thermal treatment of multi-oxide systems of combustion slag. They are the aluminates of thallium, complex crystals and the simple minerals (anorthite, melilith, pyroxens, which include the silicates such as mullite and andalusite). The practical application for these materials is the anti-corrosion cover for constructional elements of burning chamber. A comparison with the Al2O3-layers gives us a chance to propose the Tl2O3-containing composites because of their higher electro-chemical potentials for building of the geological mixtures against an aggression of hot gases. We suppose that the protective films should be created with a participation of the fly and bottom ach ingredients, but not with a permanent degradation of aluminum alloys. The second advantage is the conversion of mechanical properties for the metal acid substances with improved packing symmetry and higher viscosity characteristics of coatings from these components. We should not refuse a light toxic effect of thallium aluminates for prevention of micro-biological corruption too. In the investigations the heterogeneous solid-gas equilibriums were regarded with input of fugacities in terms of calculation for the chemical potentials. We introduce the ab initio computations of enthalpies for gaseous phase; kinetic mechanisms of formation for structures with concentration gradients; implementation of the calphad technique for the modeling of plasma sprays, molten state and condencing matter; distribution of software for metal rest substances. MeRS-data is the database operating and information system, produced and designed with aim of estimation for equilibrium concentrations and treatment for experimental results, their depositing and presentation in the form of finite element graphics, tables and three dimensional diagrams.
