[2], Lithium oxide forms along with small amounts of lithium peroxide when lithium metal is burned in the air and combines with oxygen:[3], Pure Li2O can be produced by the thermal decomposition of lithium peroxide, Li2O2, at 450 °C[3], Solid lithium oxide adopts an antifluorite structure with four-coordinated Li+ centers and eight-coordinated oxides.[4]. Place the following in order of decreasing magnitude of lattice energy. Its usage is also being investigated for non-destructive emission spectroscopy evaluation and degradation monitoring within thermal barrier coating systems. The lattice energy of NaCl, for example, is 787.3 kJ/mol, which is only slightly less than the energy given off when natural gas burns. NaF RbBr KCl. Upvote (8) Was this answer helpful?
