The technological properties of a series of granite rocks are studied, and it is shown that they can be effectively used as fluxes for porcelain mixes. It is found that low-temperature porcelain can be obtained under intensified heat-treatment. The phase composition, microstructure, and properties of the materials are studied. The effect of the properties of the liquid phase on the formation of structure and the usage and decorative properties of porcelain fabricated by energy-conserving technology are determined.

This work presents the results of optimization of the compositions area of radiotransparent ceramic. Theoretical calculation of free Gibbs energy proves the possibility of the formation of strontium anorthite phase for every composition of Sheffe plan. As a result of laboratory samples test, graphic dependences "composition-property" was obtained, the choice of the most technologically advanced composition area and sintering temperature for manufacturing the radiotransparent ceramic was substantiated. The optimal composition of the Sr-anorthite ceramics is characterized by the next level of properties: water absorption (W = 0.17 %), dielectric permittivity (ε = 5.15), mechanical strength (σ compression = 176 MPa). Streszczenie. W pracy przedstawiono wyniki optymalizacji powierzchni radiotransparentnych kompozytów ceramicznych. Teoretyczne wyznaczenie wartości entalpii swobodnej stwarza możliwość obliczenia parametrów anorytu strontu dla wszystkich kompozytów Scheffe'a. Badania laboratoryjne próbek pozwoliły na otrzymanie zależności graficznych określających właściwości kompozytu. Określono wartość powierzchni kompozytu oraz temperatury spiekania, która jest optymalna do wytworzenia radiotransparentnego materiału ceramicznego. Wyznaczono również dodatkowe wielkości charakterystyczne, którymi charakteryzuje się optymalny ceramiczny kompozyt anorytowy: absorpcja wody (W = 0.17 %), przenikalność dielektryczna (ε = 5.15) oraz wytrzymałość mechaniczna (σ compression = 176 MPa).

The article contains the results of a study of the nature and main characteristics of the national-patriotic upbringing. The study was conducted by studying and analyzing the latest regulations and publications, related issues and identifying the nature of the main characteristics of the national-patriotic upbringing. The author of the article presents the results of scientific analysis, conclusions about the need to develop formation technologies of national-patriotic education of students at schools. National-patriotic upbringing is a complex of personality traits and actual result, achieved by an individual or collective in the process of national-patriotic upbringing, manifested in the ability and willingness to be realized as an individual and collective in the service to the Motherland: learning the experience of cognitive activity by a student involves the formation of patriotic knowledge and ideas; mastering the experience of emotional and value relationships by a student means the formation of patriotic feelings, values, beliefs; mastering the student's practical experience is manifested in the implementation of patriotic knowledge and ideas, values and beliefs in patriotic behavior and activities. The essence of national-patriotic upbringing, in our opinion, is the students' learning of the experience of cognitive activity, emotional-value relationships and effective practical experience, which are manifested in the ability and willingness to be realized as an individual and collective in the activity for the benefit of the Motherland. The article can be recommended for publication in a specialized journal.
