Microsphere Silica Gel 30-100 Mesh Premium Grade

Coarse-pore microspherical silica gel appears as milky white granules, primarily composed of silicon dioxide. It is insoluble in water and inorganic acids but soluble in strong acids and strong alkalis. Its internal structure features a pore volume of 0.80–1.30 ml/g, a pore size of 80–120 Å, and a specific surface area of 300–550 m²/g.

This product is mainly used as a catalyst and catalyst carrier for important petrochemical products. It is also widely employed in the refining of petroleum products and the selective adsorption and separation of certain organic gases and liquid components. Additionally, it serves as an ion exchanger for removing harmful multivalent elements from water, as well as for the dry storage of materials and equipment, and the dehydration and purification of high-purity gases.
