The subsolidus phase relations in the system BaO-B2O3-P2O5 were determined. The system can be divided into 16 three-phase regions. There are nine binary compounds and three ternary compounds in this system.

The powder barium borophosphate BaBPO5 was synthesized by solid-state reaction techniques. Single crystals BaBPO5 with sizes up to 20 mm × 15 mm × 10 mm were grown by top-seeded solution growth method using H3BO3/sub

In order to study the mechanism of the second harmonic generation (SHG) effect in borophosphates, two large ultraviolet nonlinear optical crystals, SrBPO5 and BaBPO5, have been successfully obtained using a top-seeded solution growth method. Optical and thermal properties have been measured, and SrBPO5 and BaBPO5 are shown to display large experimental gaps (6.44 eV and 6.14 eV, respectively) and moderate SHG coefficients (0.57 and 0.43 times that of KH2PO4). More importantly, based on a further understanding of the relationship between nonlinear optical properties and crystal structure within density functional theory (DFT), we have demonstrated that BO4 groups and metal cations play an essential role in the SHG effect of SrBPO5 and BaBPO5, but not PO4 groups as anticipated. Indeed, PO4 groups play a counteractive role in BaBPO5 due to the indirect influence of metal cations.

, p. 70 - 75 (2002)
The crystal structure determination of lithium and barium nanoborates synthesized under hydrothermal conditions was reported. The structure of BaBPO5 was refined by Rietveld method in contrast to the structure of PbBAsO5, which was determined on a single crystal. The phase transformation at high temperature in the stillwellite structure type accompanied by the replacement of the polar space group was also reported. The phase expansion of the La-polyhedron was compared to BO4 and GeO4 tetrahedra.
