tér s ér s Silica Aerogels Silica Aerogels are generally known for being an extremely lightweight transparent solid (down to <0.05 g/cm3) with excellent thermal insulating properties, high temperature stability, very low dielectric constant, and extremely high surface area. Some initial applications have included atomic particle detectors and super insulation for aerospace applications and they were used to insulate the Mars rover. Silica Aerogel MSDS Our standard silica aerogel is formed into translucent monolithic blocks with carefully controlled densities. The standard density is nominally 0.1 g/cm3 with a surface area of about 800 m2/g. Densities from 0.01 to 0.30 g/cm3 are commonly available. As the silica Aerogel monolithic blocks are quite friable, we offer random pieces 0.2 to 2.0 cm for evaluation purposes. These are sold in standard packages of 10, 50, and 250 grams. Monolithic blocks up to 4" x 8" x 0.5" are standard.
