بيت /Quartz Slica Powder Production Chart
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.

Fused quartz, or silicon dioxide, to give its chemical name, was originally produced from pure quartz crystal, melted at extremely high temperatures. But while quartz crystals continue to be used for fused quartz, it has been found that when crystalline silica occurs in sand or rock, it can also produce fused quartz, or synthetic fused silica, as this manmade fused quartz is sometimes called.

Silicon dioxide has a high porosity which allows it to absorb up to 300g of fluid per 100g of silica. This means that liquid ingredients can turn into free flowing powders with ease. It acts as a glidant, a substance used in a formula to improve its flow qualities. It ensures that the product flows through machinery and doesn't stick to the equipment. Using silica will also increase the ...
