Question

resistivity = VA/LI how??​

Answer 1

hey mate!

The density, electrical resistivity and Hall constant of LiB alloys in the concentration range 0–60 at.% B are reported. The binary phase diagram of this system has not been reported in the literature and the data presented here are used to obtain information about the phases present. An analysis of the measured densities reveals that in the composition range 0–40 at.% B most of the B is present in an Li-rich phase, probably Li5B4, possibly with some Li3B also present. Up to 40 at.% B there are also significant amounts of free Li in these alloys. The electrical resistivity at room temperature was roughly constant between 0 and 45 at.% B and then increased rapidly with increasing B. The Hall coefficient at room temperature was fairly constant from 0 to 40 at.% B and then increased. The temperature dependence and magnitude of the electrical resistivity were metallic in nature and there was no evidence of semiconducting behavior at the higher B concentrations. There was a break in the resistivity of the 40 at.% B sample at the melting point of Li, indicating the presence of free Li, but no break in the resistivity of the 50–60 at.% B samples. It was possible to calculate the stoichiometry and density of the LiB phase (or phases) present in the 40 at.% B sample: 55.3 at.% Li and 1.07 g cm−3, respectively, very close to the 55.6 at.% Li and 1.0537 g cm−3 calculated for Li5B4 from a recent X-ray and neutron diffraction structure study by Wang et al.
