Barium tungsten electrode is an electron emission material composed of tungsten (W) and barium (Ba) compounds. Its thermal electron emission characteristics have important applications in vacuum electronic devices, light sources, medical and industrial fields.

Barium tungsten electrode plays a vital role in high-resolution microscopy, mainly used as an electron source, providing a high-quality electron beam to achieve high-resolution imaging.

Silicotungstic acid, also known as tungstosilicic acid or tungstosilicic acid hydrate, is an inorganic compound composed of tungsten, silicon, hydrogen, and oxygen. It is an inorganic acid formed by hydrogen ions and silicotungstate anions, with the English name tungstosilicic acid hydrate or silicotungstic acid, molecular formula H₄[Si(W₃O₁₀)₄]·nH₂O, molecular weight 2878.17, and CAS number 12027-38-2.

Like an evaporation tungsten boat, tungsten crucible is a typical product made from refractory metal tungsten, primarily using tungsten powder as the raw material. It is a high-temperature resistant vessel with the English name tungsten crucible. It generally contains over 99.95% tungsten and is typically cylindrical in shape, with diameters ranging from 10mm to 500mm, heights from 10mm to 750mm, and wall thicknesses from 8mm to 20mm.

Tungsten niobium alloy, also known as niobium tungsten alloy, is a two-phase alloy composed of two transition metals or refractory metals, similar to tungsten-molybdenum (WMo) alloys. It is widely used in aerospace, aviation, maritime, military, and defense fields due to its excellent mechanical, thermal, and chemical properties. Note: Tungsten (W) has an atomic number of 74, and niobium (Nb) has an atomic number of 41.

Like tungsten cubes, tungsten bitcoin is a beloved item among cryptocurrency enthusiasts. Made from a tungsten-based alloy, it is also known as a tungsten alloy bitcoin. Its advantages of being impervious to wear, fade, or deformation make it an ideal souvenir, collectible, or gift for friends.

Molybdenum bar is a rod-shaped product made primarily from high-purity molybdenum, with a purity of up to 99.7%. Renowned for its excellent thermal, mechanical, chemical, and electrical properties, it serves as a core foundational material in key industries such as metallurgy and power equipment.

Barium tungsten electrodes play a crucial role in high-energy particle accelerators, especially electron accelerators and free electron lasers, mainly as the core component of high-performance electron sources - electron gun cathodes. Its application value is mainly reflected in the following aspects:

Barium tungsten electrode has become an indispensable key material in high-power microwave devices through its low work function, diffuse cathode structure and environmental protection characteristics. It not only supports the high-power output and stability of the device, but also promotes the wide application of high-power microwave technology in military, industrial, scientific research and other fields.

Tungsten alloy nut is a high-performance fastening component made from refractory metal tungsten as the base, blended with auxiliary metals like nickel and iron. Its unique internal threaded hole design allows for reliable connection with bolts.
