Fumed powder

WebFumed silica is a pure, relatively reactive source of silica. It is particularly attractive for alkali-free synthesis because its sodium content is very low. However, the powder is extremely light and fluffy, and as such, is increasingly difficult to handle as the scale of a particular zeolite synthesis reaction increases. WebComparison in powder coatings: Although both fumed alumina and fumed silica are used for similar purposes to prevent blocking, their applications and performance differ, which will be mentioned as follow. Consumption rate: Consumption rate of fumed alumina in powder coating is about 0.05% and fumed silica consumption is about 0.15%.2.
