28The 4 NEXTREMA ® types of materialNo NEXTREMA ® is like another. We would like to supply you withglass-ceramic that corresponds to your requirements as preciselyas possible. This is why NEXTREMA ® is available infour types, each with different benefits.SCHOTT NEXTREMA ® transparentThe transparent variety keeps a clear head in extreme temperature environments.Particularly in infrared applications, where the material must also have the besttransparency in addition to high thermal robustness, NEXTREMA ® transparent is amaterial made to measure.SCHOTT NEXTREMA ® tintedNEXTREMA ® tinted stands out with three prominent material features:high temperature resistance, high mechanical stability, and optimized transmittanceof wavelengths for infrared.

29All four NEXTREMA ® types at a glanceSCHOTT NEXTREMA ® translucentThanks to its ideal insulation properties, NEXTREMA ® translucent is generally the numberone material where high insulation properties are required in extreme temperature environments.The fact that this type of NEXTREMA ® also has excellent resistance against chemicalattacks makes it an even more sought after solution.SCHOTT NEXTREMA ® opaqueBesides its surface resistance, NEXTREMA ® opaque glass-ceramic impresses due to itsabsolutely dense and pore-free surface. Both show why NEXTREMA ® also plays asignificant role from an aesthetic perspective. The noble opaque white sets an example.
