China, Germany, and the United States are the leading exporters of silica (CAS 10279-57-9), collectively accounting for over 45% of global exports in 2023–2024, while the United States, South Korea, and Japan remain the largest importers by value. Silica prices have remained relatively stable amid steady export volumes from major producers, though demand growth in Asia-Pacific semiconductor and construction sectors has reinforced import concentration in that region.
Silica (CAS 10279-57-9) refers to synthetic amorphous silica, typically appearing as a fine, white, odorless, non-volatile powder. It is an inorganic oxide—specifically, a hydrated form of silicon dioxide—with no defined melting point due to its amorphous structure and thermal decomposition above ~1,600 °C. Silica is widely used as a reinforcing filler, flow aid, and thickening agent across industrial applications. Its principal uses include rubber compounding (especially in high-performance tires), food and pharmaceutical processing (as an anticaking agent), and as a rheology modifier in coatings, inks, and adhesives. It also serves as a catalyst support and functional additive in polymer composites and agricultural formulations.
This chemical is included in Rubber. See more about what is Silica and Silica SDS information.
