Especially in high-temperature environments, where other materials such as plastic, conventional glass or metal show their limitations, NEXTREMA® glass-ceramics are an alternative.
NEXTREMA® is available in six types, appearances, and different shapes. This makes it easy to find the right glass-ceramic that corresponds to your requirements as much as possible. It also gives you freedom of design and room for differentiation.

In certain applications, the linear coefficient of thermal expansion and, therefore, the total change of length of a NEXTREMA® part within a specified temperature range is important to its function.
The following graph and table illustrate the temperature dependency of the thermal expansion of selected NEXTREMA® types (mean values; selected types).

The resistance of the material to temperature differences between a defined hot zone and cold edge of room temperature, without thermal stress induced cracking. NEXTREMA® offers a MTG of 400 - 800 K.
The resistance of the material to thermal shock when the hot material is splashed with cold water at room temperature, without thermal stress induced cracking. NEXTREMA® offers a TSR of 600 - 800 °C (1,112 - 1,508 °F).
NEXTREMA® offers six transmission profiles in the visible and infrared range depending on material type and material thickness.
