Coarse-pore microsphere silica gel is produced through an oil-forming and high-temperature activation process, using raw materials such as soda ash and sodium silicate. The product features low abrasion, high activity, and a long service life, making it an excellent catalyst or catalyst carrier. Coarse-pore microsphere silica gel appears white, transparent, or semi-transparent. It has a uniform microporous structure internally, with stable physicochemical properties, good thermal stability, and high mechanical strength. Its average pore diameter ranges from 8.0 to 12.0 nm.
