Quartz

Mineral: Silica/ 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)

Note when using quartz: depending on the particle size distribution of the product, it can be labelled (STOT RE 2 or STOT RE 1). For more detailed information, visit  www.safesilica.eu.

Functionalities:  Silica has good electrical insulating properties and heat conductive properties. It has a reinforcing effect and also allows the skilled formulator to make low viscosity compound that easily flows into the smallest cavities.
