SCHOTT NEXTREMA® types of material

With NEXTREMA® we offer engineers and designers a unique glass-ceramics portfolio of six material options. All six types have the following material benefits in common:
  • High temperature & thermal shock resistance
  • A non-porous, highly resistant surface
  • High chemical resistance
  • Transmission in infrared range
  • Good mechanical strength
In addition each material type has its specific material benefits that will help designers and engineers alike realize new applications, functionalities, and designs. Explore the specific material benefits and exemplary application fields by clicking on the material types.
