Without harm, silicon is the main component of silica sand.
Silica gel is very chemically stable and does not react unless it encounters strong bases. In particular, medical silicone is commonly used in breast implants, pads, etc. In daily life, pacifiers, pressure cooker seals, etc. are silicone products.
When silica gel burns in the fire, it will be reduced to silica, or silica sand, which will harm the human body. Can be used with confidence.
Silica gel itself is not toxic, but some silicones contain additives that are harmful to the human body.
Silica gel is a highly active adsorbent material and is an amorphous material. Its chemical formula is mSiO2·nH2O. It is insoluble in water and any solvent, non-toxic and odorless, chemically stable, and does not react with any substance except strong alkali and hydrofluoric acid. Various types of silica gel form different microporous structures due to their different manufacturing methods. The chemical composition and physical structure of silica gel determine that it has many other similar materials that are difficult to substitute: high adsorption performance, good thermal stability, chemical stability, high mechanical strength, etc.
