Abstract
Phase equilibriums in the binary alkaline-borate systems are investigated by means of vibration phase
analysis (VPA) and thermal analysis; melting points and types of melting are verified, as well as the composition of compounds existing in the phase diagram. The existence of the compounds of the type 2R2O? 5B2O3 and 2R2O? 3B2O3 within a narrow temperature range in all the binary systems under investigation is stated.
