Abstract

The Li2O–B2O3–H2O system has been studied under hydrothermal conditions (T = 250 °C, P < 100 bars). The phases crystallizing in this system are Li4B7O12Cl, Li2B4O7, Li3B5O8(OH)2, LiH2B5O9, and Li2HBO3. Some of these phases are new ones. Their fields of crystallization are shown in the composition diagram. The growth and characterization of these lithium borates obtained in the system Li2O–B2O3–H2O under lower PT conditions have been discussed in brief.
