بيت /silicium metal vs silica sand
Sand was more readily available than the other media. But sand had issues like moisture content that made it difficult to spread with compressed air. Sand also had a lot of contaminants found in natural supplies. The biggest challenge in using sand as an abrasive media is its health hazard. Sand used in sandblasting is made of silica.

Silica, a chemical compound found in abundance in nature, is comprised of quartz, a constituent of rock, and makes up 9095% of sand. Most silica in commercial use is obtained by processing (such as crushing or milling) from naturally occurring sources and can be found in abrasive cleaners, toothpaste, scouring powder, and metal polish.

Silica fume (SF) is a byproduct of the smelting process in the silicon and ferrosilicon industry. The reduction of highpurity quartz to silicon at temperatures up to 2000 °C produces SiO 2 vapours, which oxidizes and condense in the lowtemperature zone to tiny particles consisting of noncrystalline silica. Byproducts of the production of silicon metal and the ferrosilicon alloys having ...

Silica is one of the most common elements, and is present in many natural waters. It is found in waters in the form of (a) reactive silica, (b) colloidal silica, and (c) suspended particles (sand). Reactive silica is called silicon dioxide, and in this form is generally not ionised at normal pH levels of water [33, 37]. Colloidal silica is ...
