Sigma-Aldrich™ Silica mesoporous SBA-15 is a highly ordered mesoporous silica material characterized by its hexagonal pore morphology, high surface area (450–550 m²/g), and uniform pore size (8 nm). With particle sizes under 150 µm, SBA-15 is widely used in catalysis, separation science, adsorption, imaging, and drug delivery research.
SBA-15 silica features thick pore walls, large pore volumes (0.8–1.0 cm³/g), and exceptional thermal stability, making it an ideal support for functionalization and advanced material design.
