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:

  • Amethyst
  • Citrine
  • Milky quartz
  • Blue quartz
  • Dumortierite quartz
  • Smoky quartz
