Lithium Oxide, Formula, Chemical Properties, Preparation, Uses

Lithium Oxide

Lithium oxide is an inorganic compound which is a white solid with the pure crystalline form. It is evaluated by the amount of lithium oxide is presented. These chemical compounds reacted with the water violently to form the lithium oxide. A spodumene is the principal mineral of lithium. It can be decomposed at the temperature between 300-400C. The systematic IUPAC name is known as lithium oxide. The chemical or molecular formula of lithium oxide is Li2O. It is also known as Lithia.

Structural Formula

This is the structural formula of the lithium oxide:

Lithium Oxide

Chemical Formula

The chemical formula of the lithium oxide is Li2O.

Preparation Method

When the lithium metal is heated with the atmosphere air and mixed with the oxygen which is present in the air is reacted  and form the chemical compound is called lithium oxide. It is produced at the temperatures is above 100C. the lithium oxide has a linear bond length with the strong ionic bonding in the ground state gas phase. In the thermal decomposition at the temperature of 450C to form the lithium peroxide. The chemical reaction is given as follows.
