Unbranded Science & Education Aerogel sku-15567272455

These Unbranded silica aerogel beads are listed in Science & Education under sku-15567272455; UPC 748385594072. The listing describes a lightweight, highly transparent material for display or as a scientific gift. It also describes fragile aerogel blocks that can be crushed by hand.

They are boxed for shipping and should be stored without crushing them; size customization is available through customer service. Silica aerogel is a low-density, three-dimensional nanoporous solid formed from joined nanoscale particles or polymer molecules, with gas in its pores. The stated density is 3.55 kilograms per cubic meter, or 2.75 times that of air.

Its pores are described as smaller than 69 nm, affecting gas conduction and convection; the network structure also limits heat transfer through the solid and by radiation. The listing notes acoustic, optical and mechanical properties.
