FMJ100
Silicon dioxide aerogel is the lightest solid material because it has the characteristic of nanoporous structure (1-100nm), low density (1-500kg/m3), low permittivity (1.1-2.5), low thermal conductivity (0.013-0.025W/(m.K), high porosity ( 80-99.8%), high specific surface area ( 200-1000m2/g) etc. It shows the unique properties in mechanics, acoustics, thermology, optics. It has a broad and huge application prospect on the field of aerospace, military, communications, medicine, building materials etc.
