A caustic white powder that absorbs Carbon dioxide and water from air, lithium oxide is used in the manufacture of ceramics and glass. It is also used as a component of some metals and is an important additive in the production of some thermal batteries.

The li2o melting point is a critical parameter for the thermal conductivity of lithium-ion batteries and other fusion systems. It may be difficult to find an accurate temperature for this material if it is used as a component of a high-temperature system without being subjected to an extensive thermochemical study.

Extensive Monte Carlo simulations have been carried out of Li2O in the low temperature range 1-500 K. Quantum path-integral corrections to the enthalpy and unit cell size have been incorporated into the computations.

We determined a maximum value for the radial distribution functions g(Li-Li) and g(O-O) vs. temperature for simulations starting from solid and mixed (half-solid, half-liquid) systems. The results show that classical Monte Carlo underestimates the enthalpy and unit cell sizes in the solid.

The presence of a small amount of Li2O can make significant contributions to the viscosity and heat capacity of sodium borosilicate melts. In particular, this effect is more pronounced when the substitution content of Li2O is 0.50 mol and higher. It also has a profound effect on the strength of Si-O bonding and the fraction of [BO3] and [BO4].
