LiBOB was synthesized by an improved solid-state method. H2C2O4·2H2O was dehydrated to get anhydrous H2C2O4, and H2C2O4·2H2O was mortared with LiOH·H2O. The mixture of H2C2O4 and LiOH·H2O was preheated at 60 ℃ for 2 h before adding H3BO3 in several times to be mortared. In vacuum dryer, the mixture of the three starting materials was preheated in two steps: at 70 ℃ for 6 h and then at 100 ℃ for 3 h.

The permittivities of N, N-dimethylformamide, water (H2O), and DMF-H2O mixture solution were measured by a resonant cavity perturbation method at 2.45 GHz and 288, 298, and 313 K. The measured results showed a specific phenomenon wherein the imaginary part of the solution's permittivity was larger than that of each of the components.

The results show that the surface layer of the air-exposed ZrVFe getter is covered with H20, CO2 and hydrocarbons, both Zr and V exist in the oxidized state, and vanadium oxide starts to reduce at 200℃. The activation results in the enrichment of Zr on the getter surface and the formation of the metallic carbides. H2O, CO2 and hydrocarbons sequentially desorb from the surface with the increase of temperature. H2 is the main gas which desorbs above 200℃ and O2 is not discovered. ZrO2 is reduced to near-metallic or metallic state because O in ZrO2 leaves the getter surface through diffusing into getter bulk.
