Volumetric Feeder for Fumed Silica

Fumed silica is also known as pyrogenic silica because it is produced in flame pyrolysis of silicon tetrachloride or from quartz sand vaporized in a 3000 °C electric arc. Fumed Silica consists of microscopic droplets of amorphous silica fused into branched, chainlike, three-dimensional secondary particles, agglomerating into tertiary particles. The resulting powder has an extremely low bulk density of 2.5-11.8 lbs/ft3 (40–190 kg/m3), a primary particle size of 5–50 nm (smaller than the average p

Ignition and Combustion Mechanism of Boron Particles

What is Boron powder?Boron powder is a kind of metal fuel with high gravimetric and volumetric calorific values, which has been widely used in military fields such as solid propellants, high-energy explosives, and pyrotechnics. However, the easily formed liquid oxide layer can adhere to the surface of boron powder and react with the hydroxyl (-OH) group of hydroxyl-terminated polybutadiene (HTPB) binder to form a gel layer that is detrimental to propellant processing and restricts the complete o

Iron oxides can be synthesized

All known wet chemical methods can synthesize iron oxides, but tailoring the particle size to the nano range and the morphology toward a particular application remains challenging. Iron oxides, either Fe3O4 or γ-Fe2O3, can be prepared from aqueous Fe2+/Fe3+ salt solutions by adding a base under an inert atmosphere at room temperature or elevated temperature (Bee et al., 1995). A thermal decomposition method has been developed as an effective way to synthesize high-quality semiconductor and oxide
