说明

一般描述

Barium oxide, also known as barium(II) oxide, is a white or off-white fine powder with a melting point exceeding 1,800 °C. It is a highly stable compound with a high melting point and good chemical resistance, making it suitable for use in a wide range of applications. There are several methods to produce barium oxide including the thermal decomposition of barium carbonate and the electrolysis of barium chloride.
 

应用

Barium oxide is used in a variety of applications. It is used as a raw material in the production of ceramics, such as glazes and ceramic pigments. It is used as a refractory material in the production of furnace linings and high-temperature applications. It is used as a fluxing agent in the production of glass, helping to lower the melting point and improve the clarity of glass. It is used as a catalyst in the production of polyethylene and other polymers. It is often used as a starting material to produce other barium compounds or dope semiconductors.
