Beschreibung

Allgemeine Beschreibung

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.[1][2]

Anwendung

BaO can be used in a variety of applications such as:

• network modifier in the development of cathode ray tubes[3]
• fabrication of glasses such as crown and borosilicate glasses[4]
• storage of nitrogen gas[5]
• preparation of biodiesel for internal combustion engines[6]

Leistungsmerkmale und Vorteile

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