Quartz is a very common mineral, a chemical compound of silicon and oxygen, silicon dioxide SiO2, commonly called silica. If pure, quartz is a colorless, transparent, and very hard crystalline material of glass-like look. The well-known quartz crystal hexagonal- six-sided prisms with a six-sided pyramid at their ends - are simply well formed crystals of quartz. Quartz appears in a number of colored varieties, like amethyst (violet), citrine (yellow), or smoky quartz (gray to brown). It also occurs in dense forms with no visible crystals, like the multi-colored agate and the gray flint. Quartz is an important rock-forming mineral, being a constituent of many common rocks, like granite

Crystal, consisting of silicon (Si) and oxygen (O2), is a form of the mineral quartz - the main material in glass. Natural, transparent single crystals are found in a multitude of geometric shapes, but the best-known are hexagonal and trigonal pyramids. As symbolized by a fortune-teller's crystal ball, this mineral has long been treasured for its transparency and mystique. Crystallized varieties of quartz such as amethyst are also prized as gems.

Types of Quartz
The crystalline forms are commonly called macrocrystalline quartz, while the dense and compact forms are either called cryptocrystalline or microcrystalline quartz (sometimes authors distinguish between megaquartz and microquartz). When people talk about "quartz", they often mean macrocrystalline quartz, whereas cryptocrystalline varieties are often subsumed under the term chalcedony.

The success of our mining is built from our natural raw materials resources. The unique purity properties of our quartz crystal gives a technological advantage to customers and puts them in a higher level into the worldwide market , due to it special characteristics it use can varies to multiple industries.

Chemical properties - Quartz is a compound of one part silicon and two parts of oxygen, silicon dioxide, SiO2. Its chemical composition (and the element silicon, Si) was discovered by the Swedish chemist Jöns Jakob Berzelius in 1823. Silicon dioxide is commonly called silica. At room temperature, SiO2 in all modifications is almost inert and does not react with most other substances. Even at moderately high temperatures silica is chemically very stable. For that reason fused quartz (silica glass) is widely used for chemical apparatus, especially when catalytic reactions of the metal cations in ordinary glass need to be avoided. The reason for the low reactivity of silica is the very strong Si-O bond, but also its macromolecular structure.

Piezoelectricity - Quartz crystals have piezoelectric properties, that is they develop an electric potential upon the application of mechanical stress. An early use of this property of quartz crystals was in phonograph pickups. One of the most common piezoelectric uses of quartz today is as a crystal oscillator. The quartz clock is perhaps the most familiar device using the mineral. The same principle is also used for very accurate measurements of very small mass changes by means of the quartz crystal microbalance.
