Аmelina A. Glasses and glasscrystal materials for electrotechnical assignment on the basis of system Li2O-P2O5

Object of research - technological processes of reception of oxide-salt phosphatic glasses and glassceramic materials on their basis. The work purpose - is working out of composition and development of the scientific foundations for making of oxide-salt phosphate glasses with the increased conductivity for ions lithium for application in chemical current sources with solid electrolyte and glasscrystal materials with low thermal expansion on the base of this glasses for manufacturing heat-resistant products of electrotechnical assignment. The glass formation in multilithium region (content Li2O more 40 mole) of the oxide-salt systems Li2O-LiX-P2O5 (X - BO2-, SO42-, F-) had been investigated. By calculated thermodynamic and experimental methods is established dependence some properties of glasses (density, thermal expansion) from its composition. By refractometric method had been showed positive influence of the salts additions for glass formation ability of melts of the specified systems. For the fist time on a basis of multilithium glass in the system Li2O-Li2SO4-P2O5 with use of a principle of reactionary formation of structure is received dense b-eucriptite glassceramic materials for use as substrate of the flat electrical heater with higher power. Sphere of usage is the electronics engineering, electrical engineering.
