How do you get lithium oxide?

Answer 1

You get lithium oxide when you burn lithium metal in the air and combindes with oxygen.

4Li+O2 → 2Li2O

Pure Li2O can be produced by the thermal decomposition of lithium peroxide, Li2O2 at 450°C

2Li2O2 → 2Li2O + O2

I hope this helps (:

Answer 2

Lithium oxide can be obtained by heating lithium metal in the presence of oxygen. The redox reaction that occurs produces lithium oxide as a product. Additionally, lithium hydroxide can be reacted with a base to yield lithium oxide.
