Tinted, malleable IR glass-ceramic:
SCHOTT NEXTREMA® tinted (712-3)

NEXTREMA® tinted is a homogeneously colored (dark-tinted) infrared glass-ceramic that is incredibly robust and temperature shock resistant. It is characterized by high mechanical stability. NEXTREMA® tinted is the glass-ceramic with the highest flexural strength out of all NEXTREMA® material types: it can withstand up to 165 megapascals. Another benefit of this tinted special glass-ceramic is in the IR spectrum: it exhibits an excellent transmission capacity for infrared waves. NEXTREMA® tinted is therefore a material partner for radiant heaters and infrared heaters in industry and household.

Key properties
  • Extraordinary bending strength of up to 165 megapascals (for 4 mm-thick glass-ceramic)
  • Reduction of visible light in combination with high infrared transmission
  • Good transmittance for IR radiation
  • High degree of resistance to temperature shocks of up to 800 °C – and a linear thermal expansion coefficient of almost zero

Example fields of application
  • Attractive covers for indoor and outdoor radiant heaters
  • Glare-reducing covers for infrared heaters (e.g. in industrial drying processes)
  • Decorative element for applications in the fields of architecture, furniture and the household appliance industry
