Kong microspherical silica appears white, transparent, or semi-transparent, with a uniform microporous structure inside. It exhibits stable physicochemical properties, excellent thermal stability, and high mechanical strength. Macroporous microspherical silica is used as a catalyst carrier in the production of important industrial products and is widely employed in the refining and removal of aromatic hydrocarbons from petrochemical products. It can also be used for the selective adsorption and separation of organic gases and liquids, ion exchange to remove harmful multivalent elements from water, and the purification and separation of plants such as Artemisia annua.
