kvartskristall

Kvartskristall, often referred to as quartz crystal, is a mineral composed of silicon and oxygen atoms arranged in a framework structure. Its chemical formula is SiO2. Quartz is one of the most abundant minerals in the Earth's crust and is found in a wide variety of geological environments. It is known for its hardness, ranking 7 on the Mohs scale, which makes it relatively resistant to scratching.

Pure quartz is colorless and transparent. However, impurities within the crystal lattice can lead to a wide range of colors, resulting in various popular gemstones. Examples include amethyst (purple), citrine (yellow to orange), rose quartz (pink), and smoky quartz (brown to black). These colored varieties are often used in jewelry and ornamental objects.

Beyond its aesthetic appeal, kvartskristall possesses piezoelectric properties, meaning it can generate an electric charge in response to mechanical stress. This characteristic makes it valuable in electronic devices such as watches, radios, and oscillators, where it is used to regulate frequency. Its stability and resistance to temperature changes also contribute to its utility in various scientific and industrial applications. Quartz sand is a primary component of glass and is used in construction and abrasive materials.
