Definition - What does Quartz mean?
Quartz is a mineral found in the earth’s crust and has the chemical formula SiO2. Quartz is the second most abundant mineral (making up 12% of the crust) after feldspar silicates such as plagioclase and alkali feldspar.
As a crystal, quartz's atomic framework is held together in a silicon oxygen tetrahedral structure, where each oxygen molecule is bonded to two tetrahedral molecules.
Pure quartz is the most common material used in high-pressure digestion system vessels, which are used for matrix decomposition and mineralization procedures at high temperatures. The corrosion process is increased because quartz is a rough mineral due to its compositional shape.
Corrosionpedia explains Quartz
Quartz is considered a semi-precious stone and is available in many varieties including:
- Milky quartz
- Blue quartz
- Dumortierite quartz
- Smoky quartz
- Rose quartz
Quartz belongs to the trigonal crystal system whose shape is in the form of a six-sided prism.
