Abstract: The Na₂O－Bi₂O₃－B₂O₃ glass was prepared by abrupt cooling method. XRD showed that the performance of forming glass was very good and the extension was very wide.The test of density‚IR and TSDC showed that B element in glass was abnormal Bi element has microstructure of 〔BiO₃〕and 〔BiO₆〕. The alkali metals ion and microstructure of glass was orientated in the foreign field and showed clear SHG domino.
