Abstract. 1 The perspective of glass-ceramic high-strength materials used for personal armor elements has been established. The methodological approach has been developed and the choice of initial lithium aluminosilicate system for obtaining high-strength lightweight glassceramic materials has been substantiated. The glass formation area in the chosen system was studied, and model glasses were synthesized. Features of crystal structure formation during heat treatment of the developed model glasses were investigated. As a result, high-strength glass-ceramic materials have been developed. It has been determined that they possess high performance characteristics and can be used in manufacturing of modern composite armor.
The degree of the baddeleyite-corundum refractories erosion depending on the areas of their location in the glass-making furnace in the float glass production was established. With the use of petrographic analysis the influence of chemical and mineral composition and also temperature and gas environment on corrosion of bacor linings was studied. Due to obtained results the recommendations in relation to the increase of glass-attack resistance of the furnace and its service life length were formulated.
Abstract. Requirements to properties of protectivetechnological coatings for the tin bronze melting from secondary raw materials were formulated in the work. The choice of model glasses compositions in the initial Na 2 O-B 2 O 3 -SiO 2 system on the basis of the melting parameters values was made. Non-scarce and inexpensive raw materials for protective coatings were selected. Also the best glass composition was determined based on the complex of chosen properties. The formation mechanism of the selected composition glassy melting by using DTА and XRDА was studied.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
