Phase formation of LiB3O5 and other lithium borates in the multicomponent system NaF-B2O3-Li2O-MoO3.

Key Points

• The aim is to study phase formation and crystallization behavior of lithium borates in a specific multicomponent system.
• Analyzed primary crystallization regions of lithium borates in the NaF-B2O3-Li2O-MoO3 system.
• Investigated ternary sections of LiB3O5-NaF-Li4Mo5O17 and LiB3O5-NaF-Li2Mo4O13.
• Measured viscosity changes in the melt-solution system with varying NaF concentrations.
• Lithium triborate crystals were successfully obtained from the NaF-Li4Mo5O17 solvent system.
• Increasing NaF concentration resulted in higher viscosity of the solution.
• Crystal yield improved with the addition of NaF, confirming its role in the crystallization process.
