“…Shumov et al 27 found that more micro-inclusions occur in Li 2 O⅐3B 2 O 3 crystals obtained from solutions with 78.90 -80.17 mol% B 2 O 3 than from solutions of other compositions. The region is exactly the region of the 2Li 2 O⅐5B 2 O 3 liquidus given by Sastry and Hummel.…”

The Li 2 O-B 2 O 3 quasi-binary system is assessed. A twosublattice ionic solution model, (Li 1؉ ) P (O 2؊ , BO 3 3؊ , B 4 O 7 2؊ , B 3 O 4.5 ) Q , is adopted to describe the liquid phase. All solid phases are treated as stoichiometric compounds. A set of parameters consistent with most of the available experimental data on phase diagram and thermodynamic properties is obtained by using the CALPHAD technique.

“…The former could efficiently avoid the incorporation of heterogeneous ions into the grown crystal, but have a high inherent solution viscosity, due to a large amount of B 2 O 3 (>90 wt%) which limits the crystallization range for the high quality LBO crystal growth. 3,4 Compared with the B 2 O 3 self-flux, the MoO 3 -based flux has a low viscosity and a high solubility for LBO, which allows for a significant improvement in both size and quality of the grown LBO crystal. The growth of the LBO crystal using the MoO 3 flux has been intensely investigated by many researchers.…”

MoO 3 is an important flux for lithium triborate (LiB 3 O 5 ) crystal growth from high-temperature solutions.Although it has been widely used, the mechanism of the MoO 3 flux-induced growth of LiB 3 O 5 crystals is still not very clear. In this paper, we present a spectroscopic investigation of the Li 2 O-B 2 O 3 -MoO 3 ternary glasses/solutions, which were prepared from high-temperature MoO 3 -based solutions for LiB 3 O 5 crystal growth. By combining all the experimental data of Raman and MAS NMR, the types of structural species and the interactions between flux and solute are discussed to understand the MoO 3 flux-reduced mechanism of LiB 3 O 5 crystallization from the high-temperature solution. Considering the activities of lithium cations, an isomerization reaction is proposed to describe the structural evolution of the BØ 4 tetrahedron into the BØ 3 triangle in boroxol due to the MoO 3 flux. The transition between the boron oxide species is essential for the LiB 3 O 5 crystal growth. On cooling, the formed boroxol rings are polymerized by the re-formation of BØ 4 tetrahedrons again, and gather together to form the LiB 3 O 5 crystal phase. Finally, the MoO 3 flux-induced LiB 3 O 5 crystallization may be elucidated with the decrease of the concentration of the BØ 4 tetrahedron in high-temperature solutions.
