Synthesis and characterization of Ba2Be2B2O7

Polycrystalline barium beryllium borate, Ba2Be2B2O7, has been synthesized by the solid-state reaction method. Element analyses gave the atomic ratio of Ba:Be:B to be 2:2.11:1.92 in this compound. Scanning electron microscopic results revealed that the synthesized Ba2Be2B2O7 contained irregular grain morphology with an average size of 10 μm. Ba2Be2B2O7 powders were found to exhibit intense second harmonic generation. The suitable formation condition of the high purity Ba2Be2B2O7 is also established.
