Logvinkov S. The high-melting polyfunctional materials on the base of the compositions of the (CaO, ZrO2)-MgO-Al2O3-SiO2 system

The object is the processes with directed formation of phase composition and structure of high-melting poly-functional materials with complex of specified properties in the system (CaO, ZrO2)-MgO-Al2O3-SiO2. The purpose is the development of scientific bases of high-melting poly-functional materials creation with predictable phase composition, microstructure and physical-mechanical properties based on the development of ideas about regularities of solid-phase exchange reactions in the system (CaO, ZrO2)-MgO-Al2O3-SiO2. Methods are the basic laws of equilibrium thermodynamics, geometric-topological construction, statistical calculations and modern methods of physico-chemical analysis (infrared spectroscopy, thermogravimetry, X-ray diffraction, petrography, electron microscopy, dilatometry). The novelty is a concept that generalizes patterns and features of solid-phase exchange reactions passing with processes directed nucleation and the formation of structure that provide the necessary physical and mechanical properties and a wide range of performance materials. The results are that regularities and peculiarities of solid-phase exchange reactions in a multicomponent oxide system are obtained This system is the basis for multifunctional materials and products based on them on a flexible technological scheme. The level of implementation is all types of developed materials have been pilot production tested and implemented at PC "Kondratievsky Refractory Plant" and Illich MSW.
