Quartz

Mineral: Quartz/Silica  

 

Quartz (silica,SiO2) is the core mineral within the Sibelco group and can be found in a broad number of applications, such as glass, ceramics and polymers.

Quartz can be characterised by:

  • Relatively high Mohs hardness of 7
  • Low electrical conductivity
  • Easy to wet
  • High inertness in various media
  • Shape (depending on the source, quartz particles can have an angular or more rounded shape)
