Description

Phase equilibriums in the Li2B4O7 (Na2B4O7, K2B4O7)-N2H3H4OH-H2O systems were investigated by methods of isothermal solubility, refractometry and PH-metry at 25 deg C for the first time. Lithium and sodium tetraborates was established to form phases of changed composition mM2B4O7·nN2H3C2H4OH·XH2O, where M=Li, Na with hydrazine ethanol. K2B4O7·4H2O precipitates in solid phase in the case of potassium salt. Formation of isomorphous mixtures was supported by X-ray diffraction and IR spectroscopy methods
