The production of silica gel from the natural clay obtained from Kwali area council of Abuja was carried out using alkaline extraction followed by acid precipitation. The alkaline extraction was investigated using 4%, 15%, 25% and 30% (wt) sodium hydroxide solution at various reaction times of 1hr 1½ hr, 2hrs, 2½ hrs, 3hrs, 4hrs, 5hrs,7hrs and 8hrs.
As the production process involves vapors of chemicals (silicon containing precursors), it is called chemical vapor deposition (CVD). There are two sets of process families, one where the deposited nano-particles are directly melted to a condensed fused silica layer, and one, where the soot is accumulated and in a secondary process step ...

A byproduct of the process, silica fume, is sold to the refractory and cement industries to improve strength of their products. Silica fume also is used for heat insulation, filler for rubber, polymers, grouts and other applications.
The process usually uses some type of halo- or organosilane that is heated to a decomposition temperature. You could also purchase a few different sized silica with very high purity form Sigma.com ...
Silica fume has entered into common use in a majority of industrial countries and many developing countries. Silica fume has long since been an internationally tradable product.
sources) and the manufacturing process. ... We will see that all modern process for manufacturing bulk silica glass involve the preparation and viscous sintering of small, amorphous (glassy) silica …
Typical process until precision product is completed. Note) Since silica glass might be damaged due to a processing distortion, thermal treatment called "annealing" which removes the distortion between the processes is required, but in here such process is left out.
Silica gel is a granular, porous form of silica made synthetically from sodium silicate. Despite the name, silica gel is a solid. Silica gel is most commonly encountered in everyday life as beads packed in a semi-permeable plastic.
A production process for producing high-purity silica from a crude silica source by means of fluosilic acid, including the steps of: (a) subjecting the crude silica souce and the fluosilicic acid to a reaction in a reaction stage, so as to produce silicon tetrafluoride and water; (b) selectively evaporating the silicon tetrafluoride with respect to at least a portion of at least one impurity ...
Precipitated silica, a form of synthetic amorphous silicon dioxide, is derived from quartz sand, a crystalline form of silicon dioxide. The physical properties of precipitated silica can be manipulated during the manufacturing process to deliver products with a wide range of performance-enhancing features engineered for many different end-use applications.
