Barium Oxide, Formula, Chemical Properties, Preparation, Uses

Barium Oxide

Barium oxide is a non inflammable compound and it has been mostly used in the cathode ray tubes. It has contain highly excessive quantities that leads to the death. The barium has positively charged as the cation and oxide has negatively charged as the anion. It has the combination of barium and oxide. The systematic IUPAC name is known as barium oxide. The chemical or molecular name of barium oxide is BaO. The other names are barium protoxide, calcined baryta and baria.

Structural Formula

This is the structural formula of the barium oxide:

Barium Oxide

Chemical Formula

The chemical formula of the barium oxide is BaO. It has consists of one barium ions and one oxygen ions.

What Method the Acetamide Can Be Produced

Barium oxide can be prepared by the heating barium carbonate at the temperature between 1000 to 1450C. it gives the result of barium oxide is the product and carbon dioxide is the byproduct. In the another method, the barium nitrate is heated by thermal decomposition or barium carbonate is heated with the coke, carbon black or tar. The chemical reaction is given as follows.
