On the synthesis atmosphere influence in the technology of complex composite materials in the wide temperature range

摘要

Heterogeneous and homogeneous processes of synthesis for complex functional materials are studied by the methods of thermodynamic modeling and calculation, based on minimization of the Gibbs energy of the researched system. The conditions and products of gasification in the field of 0-2000 °C are determined for the synthesis conditions of a ceramic tile with complex composition (10-component system). All main products of interaction of components of ceramic mass (the system SiO2 - K2O - Na2O - A12O3 - Fe2O3 - CaO - MgO -TiO2 - P2O5 - SO3) and main components of air (the system N2 - O2 - CO2 - H2O) are found for the synthesis of material in the conditions of the air atmosphere at various temperatures. The character of physico-chemical influence of each components on the occurring processes is revealed, that determines a theoretical and calculation base of management and optimization of the synthesis engineering process for various functional materials.
