Using Lithium Compounds as Fluxing Agents

Fluxing agents reduce the temperature at which the batch melts. While soda ash and potash are commonly used fluxing agents, the use of lithium compounds have been increasing in the last 5 to 10 years. Producers using lithium compounds report lower melting temperature at equivalent melting energy and cullet input (Worrell et al., 2008. p.54). Due to its chemical properties (smallest ionic radius and highest ionic potential), lithium also lowers the viscosity and thermal expansion, resulting in better melting efficiencies and/or larger effective furnace capacities.

Energy Savings Potential

Recent estimates suggest that adding lithium to glass batches can reduce furnace energy consumption by as much as 5-10% (Worrell et al., 2008. p.54).
