Rubber industry
In the rubber industry, carbon black reinforcement has become a very mature technology and is widely used. It has now evolved into a non-traditional single carbon black reinforcement, and in recent years there have been many alternatives to ordinary carbon black, such as white carbon black. Studies have shown that the external specific surface area of ​​the reinforcing agent other than the micropores has a very important influence on the reinforcing performance in the re-carbon black reinforcing process. Therefore, in the carbon black industry, it is usually necessary to determine the external specific surface area of ​​the reinforcing agent to measure its performance.

At present, China is in the period of great development of the construction industry, and high-quality buildings are inseparable from high-quality cement. Cement as a binder, the bonding properties are closely related to the size of its specific surface area. Before the popularization of the gas adsorption method, the determination of the specific surface area of ​​the cement in the early stage was measured by the Bühler method, and the measurement results of the measurement method generally have large errors. With the improvement of cement production technology and the higher requirements of modern buildings for their quality, the results of the Böhler method are gradually unable to meet the accuracy requirements. It is a general trend to use a more precise gas adsorption method to determine the specific surface area of ​​cement.
Battery industry
With the development of industrial technology, energy issues have increasingly become the focus of social attention. The depletion of non-renewable energy and the resulting environmental pollution have forced humans to find new alternative energy sources. Electric energy, especially energy storage batteries, are generally favored because of their low pollution and regenerability. They are most likely to become alternative energy sources in the future and have broad development prospects. The key part of energy storage batteries - energy storage materials, due to the special requirements of their energy storage, the material's specific surface area performance requirements are very strict, too large or too small are unfavorable to the performance of the battery, so the specific surface area becomes the most important electrode material Physical performance indicators.
Chemical Industry
Catalysts are used in many of the chemical industry's production processes, and catalyst development has been around for a long time. With the development of material technology, the performance of the catalyst is also becoming stronger. In addition to its chemical composition, the most important determinants of the catalytic properties of materials are their specific surface area and pore volume and their surface morphology. Catalytic materials generally have a large specific surface area and are porous materials, both of which increase the contact area between the catalyst and the reactants, thereby greatly improving the catalytic performance. The specific surface area and pore volume are important performance indicators to measure the performance of the catalyst.
With the continuous development of material technology, the measurement of specific surface area and porosity (pore volume) has been widely used in many other industries, such as electromagnetic materials, fluorescent materials, ceramics, powder metallurgy, adsorbents, Cosmetics, food, etc. For particulate materials, the specific surface area gradually becomes a physical property that is as important as the particle size.
