I'm a bit curious as to who exactly calls it that; I've never heard that term before. At a guess I'd say it's probably because ordinary glass is somewhat opaque to certain frequencies of ultraviolet light, but quartz glass transmits it.
There are countless uses for quartz. The colorful transparent varieties are polished into gems. Opaque varieties are processed into ornamental items or building materials. Very pure quartz sand deposits are mined for the many items that use silicon, like computer chips.
Like all specrophotometric methods, UV/visible spectrometry is quick and simple to perform, and gives quick results. It can also detect impurities. It is cheap to perform once the equipment is bought.
Yes it does. The quartz countertops that you see in houses are engineered, but quartz also occurs in nature, and is actually pretty common.
Infrared spectroscopy cannot be used quantitatively. The sample preparation is also complex. It may be robust as the sample preparation may affect its results.
"Smelt Quartz" is commonly sold as a variety of quartz, especially from many eBay vendors. "Smelt Quartz" is not quartz at all -- it is common glass, which is made from melting quartz in the presence another compound (called a flux) which lowers the melting temperature. Glass is not crystalline, whereas quartz and other minerals (with few exceptions) are crystalline. Most people can't tell the difference, but glass is optically isotropic (doesn't polarize light) whereas quartz is anisotropic (polarizes light). Glass also has a lower density, which you might be able to detect by its heft, and "smelt quartz" usually has unnatural looking streaky patches in it."

Purple quartz is also known as amethyst.
Ultraviolet light is not visible. Many ultraviolet lamps also emit some visible light along with the ultraviolet, typically visible violet. Also, ultraviolet light is an ionizing radiation, and will cause some flourescent materials to emit various visible wavelengths of light.
It is made out of sand which is silicone dioxide also called quartz.
Quartz is and is also a mineral
No. Silicon dioxide, also called silica or, in mineral form quartz, contains only silicon and oxygen. By definition, and organic compound contains carbon.
X-ray spectroscopy is used for detecting of breakable bone in body(2)it also for internal structures
Quartz is not an element but a natural mineral (silocon dioxide, SiO2). Quartz can be obtained also in industry.
Sand is SiO2 and that is also quartz. So you will find sand on the beach.
An invisible Electromagnetic radiation (also called solar radiation) whose wavelength is shorter than visible light but greater than X-rays (i.e in ORDER of 10-8 m) is called ultraviolet wave.
There is no broken parts in quartz, so Quartz does not have cleavage.
