Silicon dioxide Usage And Synthesis
DescriptionSilicon dioxide (chemical formula: SiO2) is a chemical compound comprised of oxide and silicon elements. It is insoluble in water or acids except hydrofluoric acid. It appears as transparent to gray, tasteless crystal which is widely presented in nature as sand or quartz. It is also one of the most abundant mineral existing in Earth’s crust. It has wide applications in various fields as below: (1) as the precursor to glass and silicon; (2) for sand casting; (3) as a additive to food and pharmaceutical products; (4) for production of cement and refractory materials; (5) as the medium for conversion of energy. (6) Extraction of DNA and RNA; (7) as a defoamer component. There are many ways for production of silicon. The most common way is through mining and purification of quartz.

Chemical PropertiesSilicon dioxide/crystalline silica is a component of many mineral dusts and materials which melts to a glass at very high temperature.
UsesSilicon Dioxide is an anticaking agent, carrier, and dispersant that can absorb approximately 120% of its weight and remain free flowing. it is used in salt, flours, and powdered soups to prevent caking caused by moisture. it is also used in powdered coffee whitener, vanilla powder, baking powder, dried egg yolk, and tortilla chips. the usage level ranges from 1 to 2%. it is also termed silica, amorphous.
UsesElectronic components; piezoelectric control in filters, oscillators, frequency standards, wave filters, radio and TV components; barrel-finishing abra- sive.
UsesFormulators may select silicon dioxide (solum diaomeae) as an alternative to diatomaceous earth or clay, particularly when developing mineral make-up, pressed or loose powders. Silicon dioxide has abrasive, absorbent, and anti-caking properties, and can also reduce the transparency of a formulation. Silicon dioxide is the u.S. name for what is known as solum diatomeae.
DefinitionCrystallized silicon dioxide (silica).
HazardAvoid inhalation of fine particles.
Safety ProfileConfirmed carcinogen with experimental carcinogenic, tumorigenic, and neoplastigenic data. Experimental poison by intratracheal and intravenous routes. An inhalation hazard. Human systemic effects by inhalation: cough, dyspnea, liver effects. Incompatible with OF2, vinyl acetate. See also other silica entries
Potential ExposureCristobalite is used in the manufacture of water glass, refractories, abrasives, ceramics and enamels. Quartz is used as a mineral, natural or synthetic fiber. Tridymite is used as a filtering and insulating media and as a refractory material for furnace linings. Workers are potentially exposed to crystalline silica in such industries as granite quarrying and cutting, foundry operations; metal, coal, dentistry, painting, and nonmetallic mining; and manufacture of clay and glass products.
First aidIf this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, get medical attention. Give large quantities of water and induce vomiting. Do not make an unconscious person vomit.
IncompatibilitiesViolent reactions with powerful oxidizers: fluorine, chlorine trifluoride; manganese trioxide; oxygen difluoride, hydrogen peroxide, etc.; acetylene; ammonia.
