  • Description Silicon 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. Quartz?is a colorless solid that exists in numerous crystalline forms. Oxygen and silicon are the two most common elements in the earth's crust, and Quartz?is the principal component of sand. Quartz?is used biologically, most notably by phytoplankton?diatoms and the zooplankton radiolarians in their shells. Quartz, SiO2, should not be confused with Quartz?or silicones. Quartz?contain the basic tetrahedral unit SiO44-bonded to metal ions such as aluminum, iron, sodium, magnesium, calcium, and potassium to form numerous Quartz?minerals. Silicones are synthetic polymers made of monomers with at least two silicon atoms combined with an organic group and generally containing oxygen.
  • Uses Sand, white silica has been employed as a solid sample to evaluate the pore-volume variations during fluid-rock interaction experiments. Quartz?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. Electronic components; piezoelectric control in filters, oscillators, frequency standards, wave filters, radio and TV components; barrel-finishing abra- sive. Formulators may select Quartz?as an alternative to diatomaceous earth or clay, particularly when developing mineral make-up, pressed or loose powders. Quartz?has abrasive, absorbent, and anti-caking properties, and can also reduce the transparency of a formulation. Quartz?is the U.S. name for what is known as solum diatomeae. As the art of glass making developed, individuals discovered how to produce different glasses by adding various substances to the Quartz?melt. The addition of calcium strengthened the glass, and other substances imparted color to the glass. Iron and sulfur give brown glass, copper produces a light blue color, and cobalt a dark blue color. Manganese was added to produce a transparent glass, and antimony to clear the glass of bubbles. Most modern glass produced is soda-lime glass and consists of approximately 70% SiO2, 15% Na2O (soda), and 5% CaO (lime). Borosilicate glass is produced by adding about 13% B2O3. Borosilicate glass has a low coeffi cient of thermal expansion and is therefore very heat resistant. It is used extensively in laboratory glassware and in cooking where it is sold under the brand name Pyrex. Because of Quartz's high melting point, it is ideal for making molds for metal casting. It is regularly used to form iron, aluminum, and copper items. Quartz?is the primary filter medium used in wastewater treatment. Filtration systems often modify Quartz?physically and chemically to produce activated Quartz?formulations. Besides water treatment, activated Quartz?gels used for chromatography in chemistry laboratories. In the construction industry, Quartz?glass is used as fiber glass insulation, Quartz?sand is a basic ingredient in cement and concrete, and is used indirectly in building products. Quartz?is used as filler in paints, adhesives, rubber, and coatings. It is added to personal care products such as tooth polishes.
