The solubility of ammonium metatungstate (AMT) in water is one of its key physicochemical properties, attracting significant attention due to its wide applications in industry, catalyst preparation, and tungsten compound production.

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:

Barium tungsten electrodes excel in electron emission efficiency, brightness, and resistance to poisoning, making them suitable for HID lamps, strobe lights, and other similar applications. Lanthanum tungsten electrodes, on the other hand, offer advantages in welding stability, arc column control, and safety, and are widely used in precision welding in the aerospace industry. Below is a detailed comparison:

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.
