Barium tungsten electrode is a cathode material widely used in electron tubes and gas discharge tubes. It occupies an important position in related fields due to its unique properties.

Barium tungsten electrode is an electrode material designed to improve the performance of electron emission. Its composition and structure are precisely designed to meet the special needs of high-intensity gas discharge lamps and other fields. The following is an explanation from four aspects: composition, structural characteristics, preparation process and performance advantages:

The barium tungsten electrode is a highly efficient thermionic electron emission cathode. Its working principle is based on the reduction of the work function of the tungsten substrate surface by the active substance of barium, thereby significantly improving the electron emission efficiency. The following is a detailed analysis of its working principle:

Barium tungsten electrode is a composite electrode material made of tungsten (W) and barium (Ba) compounds, mainly used in electron emission devices such as cathode ray tubes (CRTs), X-ray tubes and electron guns. It combines the high melting point, corrosion resistance and mechanical strength of tungsten with the low work function characteristics of barium to achieve efficient thermal electron emission.
