YAAVIK MATERIALS AND ACS MATERIALS PRESENTS SBA-15 in India.
Santa Barbara Amorphous-15 (SBA-15) is a highly stable mesoporous silica sieve developed by researchers at the University of California at Santa Barbara. It gets it high hydrothermal and mechanical stability from a framework of uniform hexagonal pores that feature a narrow pore-size distribution and a tunable pore diameter of 5nm to 15nm, but, most significantly, from its relatively thick walls, which range between 3.1nm and 6.4nm. SBA mesoporous silica 15 has a high internal surface area, which lends itself to various applications, including environmental adsorption and separation, advanced optics, and catalysts.
Mesoporous silica SBA-15 is synthesized in acidic conditions using triblock copolymer Pluronic 123 (EO20PO70EO20) as a pattern and tetraethoxysilane (TEOS) for the source of silica. Once synthesis is complete, the organic template is removed by a variety of methods, including calcination; reflux extraction; H2O2 treatments; microwave digestion; and/or washing with pure solvents, ethanol, acetone, or water. ACS Materials’ SBA-15 was calcined in air at 823 Kelvin for 6 hours, resulting in a fine, white powder.
