When you search Silicon Dioxide, some related terms will appear, such as Aluminum silicate, amorphous silica, attapulgite, bentonite, calcium silicate, crystalline silica, diatomite, fuller's earth, hectorite, kaolin, lithium magnesium silicate, lithium magnesium sodium silicate, magnesium aluminum silicate, magnesium silicate, magnesium trisilicate, monomeric silicic acid, monosilicic acid, montmorillonite, orthosilicic acid, pyrophyllite, quartz, SiO2, Si(OH)4, silicate, silicic acid, sodium magnesium silicate, zeolite, zirconium silicate and etc.. Silicon Dioxide, it's chemical formula is SiO2.

Here are the background of Silicon Dioxide. Silicon is the second-most abundant element in the earth's crust, while oxygen is the most abundant element in the earth's crust.Silicon Dioxide formed: It binds to oxygen, forming crystalline or amorphous silica (silicon dioxide, SiO2), silicic acid (Si(OH)4), and silicates, such as quartz. Silicon is present in rocks, soil, sand, and dust as crystalline silica. Silicic acid is formed naturally from silica and is readily absorbed in the human gastrointestinal tract. As for biological processes: Silicon is an ultratrace element, meaning that it is suspected as being required in quantities of less than 1 milligram, but is associated with no known essential role in biological processes. A recommended dietary allowance (RDA) or adequate intake (AI) has not been established for silicon.

In our daily life, Silicon is necessary, glass component is a mixture of Na2SiO3, CaSIO3 and Silicon Dioxide. In the diet, silicon is found mainly in drinking water and plant-based foods, such as beer, unrefined grains (oats, barley, rice, and wheat bran), fruits, vegetables (spinach), and beans (red lentils). Silicon in medicine and cosmetics areas are widely used. Silicon is included as silicates in cosmetic and pharmaceutical preparations. Silicates are also added to processed foods and beverages, where they serve as anticaking agents, thickeners, and stabilizers, and they are used as clarifying agents in beer and wine. Silicon is biocompatible and has been used in many implantable medical devices, including pacemakers, defibrillators, stents, materials for plastic and reconstructive surgery (including breast implants and bone grafts), devices for sustained-release delivery of drugs, sheeting (to treat and prevent the formation of scars following surgery), and liner sockets, or sleeves. Some studies show that silicon is essential in humans body especially for bone growth and health and development of other tissues.
