Synthesis and characterization of Ba2Be2B2O7

Polycrystalline barium beryllium borate, Ba2Be2B2O7, has been synthesized b y the solid-state reaction method. Element analyses gave the atomic ratio o f 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 mum. Ba2Be2B2O7 powders were found t o exhibit intense second harmonic generation. The suitable formation condit ion of the high purity Ba2Be2B2O7 is also established. (C) 2001 Elsevier Sc ience B.V.
