Optical, mechanical, and thermal properties of barium borate
TL;DR: In this paper, Chen et al. report measurements of all the material constants necessary to fully characterize barium borate as a nonlinear optical material, including the crystal structure, the optical absorption, the refractive indices from the UV to the near IR, the thermo-optic coefficients, the non-linear optical or coefficients, resistance to laser damage, the elastic constants, the thermal expansion, thermal conductivity and dielectric constants, and the fracture toughness.

A contribution to borate crystal chemistry: Rules for the occurrence of polyborate anion types
TL;DR: In this article, the structural features of over 460 anhydrous oxoborates that are described in literature were analysed. And the Lewis acid strengths for all cations other than B 3+ that were found in these structures, using the valences of the cations and their determined average coordination numbers.
