Quartz CAS#14808-60-7

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.

Product Application of Quartz CAS#14808-60-7

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.

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.
