Lithium carbonate - Wikipedia, the free encyclopediaDilithium carbonate, Carbolith, Cibalith-S, Duralith, Eskalith, Lithane, Lithizine, Lithobid, Lithonate, Lithotabs Priadel is polymeric. It is slightly soluble in water: only 1.33 grams dissolve in 100 mL at room temperature(Around 22 Degrees Celsius). Its solubility decreases at higher temperatures. The isolation of lithium from aqueous extracts of its ores capitalizes on this low solubility.
