Quartz
Quartz (/ˈkwɔːrts/), from the German word "Quarz", is a hard, crystalline mineral composed of silicon and oxygen atoms. The atoms are linked in a continuous framework of SiO4 silicon-oxygen tetrahedra, with each oxygen being shared between two tetrahedra, giving an overall chemical formula of SiO2.
Etymology
The word "quartz" is derived from the German word "Quarz", which was imported from Middle High German, "twarc", which originated in Slavic, cf. Czech tvrdý ("hard"), Polish twardy ("hard"), Serbian and Croatian tvrd ("hard").
Types of Quartz
Quartz occurs in different forms including Amethyst, Citrine, Milky Quartz, Rose Quartz, and Smoky Quartz. Each type of quartz may be used for different purposes in various fields such as jewelry, construction, and electronics.
Medical Uses
In the medical field, quartz is used in an indirect way. The main use of quartz in the medical industry is for the manufacturing of medical tools and equipment. For example, quartz glass can be used in various medical devices due to its excellent properties such as high temperature resistance, good thermal stability, and excellent transparency.
