Variety of quartz glass
Choosing an appropriate quartz glass material or an applicable graduation of material quality is significant for successful processing.
Apart from form and function, the adequate basic material and the appropriate graduation of material quality are a crucial factor for a successful application.
Outstanding material characteristics of quartz glass
A raw material that meets the highly specified demands for industrial and research purposes
Transparent quartz glass as well as fused silica provide a range of properties that no other raw material combines in such a perfect way:
- Extremely low thermal expansion
- Excellent elasticity and thermal shock resistance
- High transformation temperature and high softening temperature
- Low thermal conductivity
- Low dielectric loss
- Good level of optical permeability in the ultraviolet and infrared spectral range
- Purity
- Corrosion resistance
- Effective as diffusion barrier against most substances
