Remarks  

Usually we use Floating Zone Material. For special applications Silicon will be produced at a resistance of >10kΩcm. Max. temperature for application: 300°C. Reacts in combination with HF and HNO3. Unsoluble in acids.

Remarkable 
  • Wide range of applications (Optic and Electronic branch)
  • IR window for 3-5 µm, FIR / Terahertz window, beam splitter, filter substrate
  • Wafer / substrates with different orientations for semiconductor electronics
  • The maximum available diameter depends on the quality (Cz-> 18 ", Fz-> 200 mm)
  • Available in different qualities (FZ = float zone, Cz = Czochralski)
