Fumed silica Wikipedia
Fumed silica with surface area of 130 m 2 /g. Fumed silica (CAS number ), also known as pyrogenic silica because it is produced in a flame, consists of microscopic droplets of amorphous silica fused into branched, chainlike, threedimensional secondary particles which then agglomerate into tertiary particles. The resulting powder has an extremely low bulk density and high surface area.

Classification of igneous rocks The Australian Museum
Silica (SiO2) content also controls the minerals that crystallise and is used to further classify igneous rocks as follows: Acid: rocks with above 63% silica (mostly feldspar minerals and quartz), granite. Basic: rocks that are about 45 to 55% silica (mostly mafic minerals plus plagioclase feldspar and/or feldspathoid minerals), basalt.
Scalable synthesis of sub100 nm hollow carbon nanospheres ... Springer
Sub100 nm hollow carbon nanospheres with thin shells are highly desirable anode materials for energy storage applications. However, their synthesis remains a great challenge with conventional strategies. In this work, we demonstrate that hollow carbon nanospheres of unprecedentedly small sizes (down to ∼ nm and with thickness of ∼ nm) can be produced on a large scale by a ...
Reevaluation of silicon dioxide (E 551) as a food additive EFSA
The EFSA Panel on Food Additives and Nutrient Sources added to Food (ANS) provides a scientific opinion reevaluating the safety of silicon dioxide (E 551) when used as a food additive. The forms of synthetic amorphous silica (SAS) used as E 551 include fumed silica and hydrated silica (precipitated silica, silica gel and hydrous silica).

Preparation and characterization of ultrafine silica ScienceDirect
Abstract. Silica dispersions of size ranging from 2060 nm with solid content ranging from 12 wt.% were prepared by hydrolysis followed by condensation of TEOS in methanol. Aqueous dispersions were prepared by adding appropriate amounts of water to the dispersion and removing the methanol by vacuum distillation in a rotary evaporator.
Green chemical conversion of largescale ... ScienceDirect
Chemical nature of aluminosilicatestozeolites conversion. The chemical nature of largescale aluminosilicates is simple. They are essentially a broad range of minerals constructed from [AlO 4] tetrahedra [AlO 6] octahedra, and [SiO 4] tetrahedra [24, 25].These polyhedra bind together via the shared oxygen with different topological structures, resulting in rich crystal structures.
