Barium tungsten electrode and thoriated tungsten electrode are two common tungsten-based electrode materials, which are widely used in welding, electric light sources, electronic devices and other fields. The following is a comparative analysis from five dimensions: component characteristics, performance, application field, environmental safety and market trend:

Transmission electron microscope (TEM) is a key analytical tool in the fields of materials science, nanotechnology and life sciences. Its core performance depends on the electron emission efficiency and stability of the electron gun. As the core material of the hot cathode electron source, the barium tungsten electrode significantly optimizes the imaging resolution and stability of TEM by reducing the work function and improving the electron emission ability.

Barium tungsten electrodes are composite materials made of tungsten and barium oxide. Due to their low work function, high thermal stability, and excellent electron emission properties, they are often used in detector components that require efficient electron emission or signal amplification. A low work function means that electrons can more easily escape from the electrode surface, providing a foundation for efficient electron emission. High thermal stability ensures that the electrode can maintain stable performance in high-temperature environments without easily deforming or experiencing a decline in performance.

A spectrometer is a precision instrument used for compositional analysis based on the absorption, emission, or scattering properties of substances with light. By resolving composite light into monochromatic components of varying wavelengths, it generates characteristic spectra to enable qualitative and quantitative identification of material compositions. Spectrometers find extensive applications in fields such as material characterization, environmental monitoring, and industrial inspection.

Barium tungsten electrode may be used as an efficient electron emission source in night vision equipment, and the photoelectric conversion efficiency is improved by combining the low work function of barium with the stability of tungsten. Its application is mostly seen in traditional or special night vision equipment, especially in scenes that require high current density or specific infrared response.

Barium tungsten electrodes, owing to their unique physicochemical properties, demonstrate extensive application potential in plasma generation devices. As a core electron emission source, their low work function and high current density characteristics provide critical support for the diversified applications of plasma technology.

The barium tungsten electrode used in electropulse sterilization equipment is a high-performance electrode material. Its core advantages lie in the combination of tungsten's high melting point, corrosion resistance, and barium's low work function characteristics.

In plasma equipment, barium tungsten electrodes are frequently used as cathode materials due to their superior electron emission properties and high-temperature resistance. Below is a concise overview of the applications of barium tungsten electrodes in plasma equipment:

CTIA GROUP LTD’s Ammonium Metatungstate (AMT), a white or slightly yellowish crystalline powder, is highly water-soluble, in stark contrast to the sparingly soluble ammonium paratungstate. As a critical inorganic chemical raw material, AMT is widely used across multiple industries. In tungsten metal production, AMT serves as a core precursor, transformed through complex reactions into high-purity tungsten powder for aerospace and electronics. In fire-resistant fabrics, AMT imparts superior flame-retardant properties, used in firefighter suits and fireproof curtains. In the ceramics industry, AMT enhances hardness, wear resistance, and high-temperature stability for architectural and industrial ceramics. Notably, in waste gas treatment, AMT-derived catalysts facilitate the conversion of harmful gases, contributing to environmental protection and cleaner skies.

Fire-resistant fabrics, engineered with special treatments or additives like flame retardants, slow or prevent flame spread and reduce burning rates. These properties provide critical time for escape during fires, minimizing harm to life and property.
