High-pressure gas discharge lamps (HID lamps), as efficient light sources, are widely used in road lighting, industrial lighting, and specialized fields. The material selection for their core component—the electrode—directly impacts lamp performance. Barium tungsten electrodes, a composite electrode material, significantly enhance electron emission efficiency by incorporating barium into pure tungsten, representing a key technological breakthrough for HID lamps.

Barium tungsten electrodes significantly enhance the performance of high-intensity discharge (HID) lamps by combining the physical stability of tungsten with the superior electron emission properties of barium. They are a critical component in high-efficiency, long-life lighting technologies.

Barium tungsten electrodes are high-performance electrode materials widely used in high-intensity gas discharge lamps (e.g., xenon flash lamps). Their core advantages lie in their exceptional electron emission capability, high-temperature resistance, and long lifespan, making them an ideal replacement for traditional thorium-tungsten electrodes.

The solvent extraction method, known for its high separation efficiency, excellent product purity, and suitability for continuous production, is a key process for producing ammonium metatungstate (AMT). This method leverages the distribution difference of tungstate ions between aqueous and organic phases to achieve separation and enrichment.
