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.
