Silicon Dioxide Nanofiber Materials

SiO2 silicon dioxide, silica, silica dioxide

Silicon dioxide is one of earth’s most abundant resources. Electronics, glass, and advanced coatings are just a few of the many applications that take advantage of silicon dioxide’s characteristics.

Silicon dioxide (SiO2), more commonly referred to as silica, is usually a transparent solid, but in nanofiber form appears as a white flake-like material. It is commonly available as an amorphous structure (glass). Silicon dioxide is a somewhat hard material that is an excellent electrical insulator (dielectric), has low thermal conductivity, can be used as a catalyst carrier, is chemically inert and non-toxic, and exhibits exceptional thermal shock resistance.

 

MemPro’s silica nanofibers are available as an amorphous material with narrow fiber diameter distributions (ave. 100 – 200 nm).
