General description

Barium Oxide (BaO) is a white ionic crystal that has a non-flammable nature. It is a cubic structured compound that can be prepared by different methodologies, such as thermal decomposition of barium nitrate, and by heating barium carbonate with carbon black or tar.

Application

BaO can be used in a variety of applications such as:
  • network modifier in the development of cathode ray tubes
  • fabrication of glasses such as crown and borosilicate glasses
  • storage of nitrogen gas
  • preparation of biodiesel for internal combustion engines

Features and Benefits

Used in the synthesis of the high-κ material BST (barium strontium titanate). Used in the study of NOX storage.
