Quartz
Mineral: Quartz
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)
