In recent years, with the development of low-voltage electrical industry, various series of new circuit breakers have been introduced. These new circuit breakers require contact materials with smaller volume and higher breaking capacity. At present, the matching of AgWC₁₂C₃ and AgW50 is often used as asymmetrical and reasonable matching contacts of circuit breakers in AgWC-C electrical contact materials, so as to improve the arc resistance and material transfer resistance of AgWC-graphite electrical contact materials, which is the necessary condition for expanding the application range of AgWC-graphite contact materials and meeting the increasingly stringent performance requirements of circuit breakers for contact materials.

Tungsten trioxide is recognized as an excellent electrochromic material. It has excellent properties in electrochromic, catalytic and gas sensitivity. Tungsten bronze, a composite oxide of tungsten bronze, generally refers to metal oxides with deep metallic luster, and is usually metal conductors or metal semiconductors.

Adipic acid is an important organic dibasic acid, which is mainly used in synthetic fibers, namely nylon-66. The annual consumption of adipic acid is very large. At present, the traditional production process of adipic acid synthesis is still widely used in industry, that is, using concentrated HNO₃ as oxidant. This process is very harmful to the environment.

With the increasing consumption of petroleum resources, the new synthetic route of preparing high value-added liquid chemicals and other organic chemicals with natural gas as an alternative energy source has attracted great attention from all over the world. The preparation of syngas by partial oxidation of natural gas is an important intermediate link in the realization of natural gas conversion, and the research and development of efficient catalysts is the key.
