Thermodynamic Assessment of the Lithium‐Borate System

“…As to the phase relations in the B 2 O 3 -rich region, there are some disputes between Rollet and Bouaziz 2 and Sastry and Hummel: 3 (1) Rollet and Bouaziz reported that Li 2 O⅐4B 2 O 3 has a hightemperature polymorph, which was not found by Sastry 26 noticed the presence of Li 2 O⅐2B 2 O 3 and Li 2 O⅐4B 2 O 3 impurities, but whether they are the products of decomposition is still doubtful because inclusions of pure B 2 O 3 and amorphous phases were also observed. Nihtianova et al also observed the decomposition of Li 2 O⅐3B 2 O 3 upon mechanical grinding.…”

Borate Materials in Nonlinear Optics

“…[69] A great problem with the growth of LiB 3 O 5 from B 2 O 3 fluxes is the rather high viscosity and the resulting low diffusivity of the melt. To reduce melt viscosity, fluxes such as LiF and MoO 3 have also been applied, but offered no significant improvement in crystal quality.…”

“…Other related investigations, including on the nucleation thermodynamics of the Li 2 O-B 2 O 3 system, the physical properties of the LBO-B 2 O 3 melt, the surface stability of the LBO crystal, critical growth parameters, post-growth thermal treatment, crystal morphology, and crystal defects, have also been carried out, and some important results have been obtained [112][113][114][115][116][117][118][119][120][121][122].
