Porous Alumino-Silicate Aluminosilicate Glass disks have a porous microstructure that gives them unique properties such as low density, high surface area and high absorption capacity. With their open porous network, these disks can be used as a substrate for catalysts, as a filter material, or as an absorber in chemical processes. Their porous structure also makes these glass disks highly insulating against heat flow.
