The objective of this work is to investigate the effect of alkali content and temperature on the microstructure of lithium borate glasses, $x$Li$_2$O${}\cdot{}$$(1-x)$B$_2$O$_3$. We have applied the molecular dynamics technique with Ewald summation and periodic boundary conditions to a collection of ca. 256 particles confined within a primitive cubic cell and interacting through a Born-Mayer-Huggins type of potential augmented with three-body angular terms. The results of this study have been discussed in relation to experimental structural data obtained by NMR and infrared spectroscopies.
