Objectives of the discipline: the formation of students' knowledge and
practical skills in the fields of physics, chemistry and technology of refractory nonmetal and silicate materials.
7. The results of the development of the module (discipline)
After studying the discipline Bachelor can:
- apply theoretical knowledge in the field of physics and chemistry of refractory
non-metal and silicate materials in the study and development of technological
processes of creation of high-performance materials and products from ceramics,
knitting, glass, glass ceramics and composites based on them;
-independently replenish own knowledge of the physical chemistry of silicates,
oxides and oxygen-free refractory inorganic substances, including the doctrine of
phase equilibrium in systems of these substances at different temperatures to
complete the melting;
- independently carry out a qualitative and quantitative calculations of phase
diagrams of binary and ternary systems and to predict probable situation, phase
correlation and structure of materials, using a one-component, two-and threecomponent systems.
8. The content of the module (Discipline) (the list of the main topics (sections).
General concepts of oxide compounds and their structure.
Silicon Chemistry.
Spread silicon, silica and silicates in the earth's crust.
Review of structures and methods of the formulas of silicates: silicates with
isolated tetrahedrons and isolated groups tetrahedrons (ring silicates); silicates with
chain polymerization of the tetrahedra - pyroxene; Band silicates - amphibole;
layered silicates; framework silicates.
Isomorphic substitution in silicates.
The doctrine of the phase equilibria and phase diagrams of silicate and oxide
systems. Heterogeneous and homogeneous silicate system. The equation of phase
equilibrium. Application of the phase rule in silicate systems. Enantiotropic
monotropic and transformation. Equilibrium conditions in silica-component
system modifications SiO2, SiO2 crystalline modifications and their natural
varieties.
Types of phase diagrams. crystallization Way - moving points, representing a
mixture of solid and liquid phases. Payment options for diagrams of twocomponent systems: graphical and analytical. Key double silicate systems.
The structure of silicates, oxides, and other refractory compounds in a
condensed state. Types of crystalline lattices. Structure oxides as dense packing of
oxygen atoms. Rules of formation of structures of ionic crystals.
General properties of the glassy state of matter. Crystallization capacity and the
rate of crystallization. Preparation of silicates in the glassy state. Factors
determining the propensity of silicate and oxide systems of vitrification. Silicates
and oxides in the liquid state.
Three-silicate systems and their physical and chemical characteristics. The most
important ternary silicate systems: CaO-Al2O3- SiO2, Na2OAl2O3SiO2,
MgOAl2O3SiO2, K2OAl2O3SiO2. Physico-chemical characterization of
compounds formed in the system; properties of the compounds, the practical
application.
