About Silica nanopowder, spec. surface area 175-225 m2/g (BET), 99.8%

Vaqora Chemicals supplies Silica nanopowder, spec. surface area 175-225 m2/g (BET), an oxide nanoparticle registered under CAS number 7631-86-9 with a typical assay of 99.8%. With the molecular formula O2Si, it has a molar mass of 60.08 g/mol. The IUPAC name is dioxosilane. Common synonyms include Silicic anhydride and Diatomaceous silica.

The material typically appears as a white powder. Literature values give a melting point of above 1600 °C and a boiling point of 2230 °C. Keep the container tightly sealed and store it in a cool, dry area. The GHS classification uses the signal word “Warning”, so appropriate gloves, eye protection and ventilation are recommended.

Key uses span nanocomposites, catalyst supports, coatings and ceramics and catalysis. Typical end-use sectors are academic and industrial research and paints and coatings.

Vaqora Chemicals supplies Silica nanopowder, spec. surface area 175-225 m2/g (BET) in 100 g, 500 g and 1 kg packs, each shipped with a Certificate of Analysis (COA), and exports worldwide.
