Lithium borate glasses
WebLithium borate samples containing PbO and LiCl were studied by Wang et al. [350] with 7 Li MN experiments. Two activated dynamic processes were found in glasses with only PbO. For a glass 66Li 2 O–11PbO–23B 2 O 3, the two processes showed activation energies of 0.11 and 0.39 eV. Web1 aug. 2012 · No systematic study has been done to investigate the scintillating properties of lithium borate glasses doped with Nd. Electrical conductivity of binary Li 2 O-B 2 O 3 glasses is studied and the conductivity was found to be ionic nature due to small size of the ion, low mass and large electropositivity [10] .
