The chemistry of silica and its potential health benefits

There are several water soluble forms of silica referred collectively to as silicic acid (ortho, meta, di, and tri-silicates), which are present in surface and well water in the range of 1--100 mg/L. Orthosilicic acid is the form predominantly absorbed by humans and is found in numerous tissues including bone, tendons, aorta, liver and kidney.

2011-11-1  Research highlights SiC nanoparticles were synthesized by silica with graphite at 1450 °C for 1 h. Fe contamination during milling act as catalyst and increased SiC yield. Leaching treatment led to leaving behind single phase SiC nanoparticles. Size of SiO 2 and milling time affected on the size and morphology of SiC. SiC from micro silica and nano silica were 20–70 and 5–25 nm, respectively.
