NEXTREMA glass-ceramic is a glass offering maximum resistance to thermal shocks of up to 820°C. It is renowned for its high transmission of light and infrared radiation, which makes it a particularly popular glass in the fields of industry and housing.
What is a ceramic glass?
Glass-ceramic is a type of glass specially designed to withstand very high temperatures. “Vitroceramic” means all the micro crystals dispersed on a vitreous phase. These glasses are renowned for resisting temperature changes and are almost invulnerable to thermal shocks.
Glass-ceramics are frequently used in our kitchens, dishes and hobs, oven glass, etc. But it is used in many other areas requiring a material resistant to high temperatures, such as in chimneys for the doors of wood and pellet stoves, inserts and fireplaces.
The advantages of NEXTREMA glass-ceramic
NEXTREMA glass is renowned for its impressive resistance to thermal shock. It has excellent infrared transmission properties, which makes it a reference material very often used as a cover for electric barbecues, infrared saunas, heating, etc. It is also used in certain industrial processes such as paint drying or welding.
The main advantages of NEXTREMA glass:
- Withstands extremely harsh conditions.
- Several colors available with various properties.
- Heat resistant up to 950°C (depending on material).
- Infrared permeable.
- Blocks UV.
- Has a non-porous surface.
- Very low linear thermal glass expansion coefficient.
Nextrema offers six glass-ceramic glass variants with varying visible and infrared light transmission profiles.
The six NEXTREMA variants and their unique properties
NEXTREMA clear glass
Compared to the other six variants, Nextrema transparent glass is the one offering the maximum resistance to thermal shock.
Nothing affects this glass, not even ice or fire. Its coefficient of expansion is close to zero, which means that it resists heat perfectly well. It has very high shortwave light transmission in the infrared spectrum.
The use of Nextrema transparent glass
This transparent universal glass is widely used in the industrial field, especially when there is a need to monitor interior mechanisms that must be visible at high temperatures.
This glass is often used for heating element plates and inspection windows for high temperature
NEXTREMA® translucent white (724-5)
This translucent white Nextrema glass has a high infrared transmission. Glass-ceramic has the widest infrared transmission range of all the other variants.
It is renowned for its high chemical resistance even in contact with very aggressive acids.
This translucent white glass reduces visible light while having high infrared transmission.
The use of Nextrema translucent white glass
This variant is often used for anti-glare covers for radiant heaters, cover plates, heated beds for 3D printers, etc.
NEXTREMA® opaque white (724-8)
Durable opaque white vitroceramic glass capable of withstanding high temperatures of up to 950°C.
This type of glass has a low transmission in the short-wave infrared spectrum, thus offering excellent thermal insulation.
This opaque white glass-ceramic is perfectly resistant to chemical elements, acids and the most extreme and demanding conditions.
This opaque white glass also brings a touch of aesthetics and design when in use.
The use of Nextrema opaque white glass
It is used for the interior linings of ovens in clean rooms, cover plates, decorative elements or even for light diffusers.
NEXTREMA® tinted (712-3)
This tinted glass-ceramic is distinguished by its high resistance to thermal shock. It has the highest resistance to bending (effect of wind, snow, etc.) of the different NEXTREMA variants (up to 165 MPa).
This tinted glass reduces visible light while having excellent infrared transmission. It has almost zero thermal expansion, which makes it very robust.
The use of Nextrema tinted glass
This Nextrema tinted glass-ceramic is used for radiant heater covers (interior and exterior), anti-glare covers for infrared heaters as well as for decorative elements (furniture, household appliances).
NEXTREMA® translucent blue gray (712-6)
NEXTREMA translucent blue-grey vitroceramic glass is appreciated and renowned for its strong transmission of infrared waves. It has the particularity of offering a so-called “dead-front” lighting effect meaning that, seen from above, the parts below are not visible at all despite the light which continues to shine from below.
This translucent glass also has a high resistance to bending (150 MPa). Its design is unique and its color very attractive.
The use of Nextrema translucent blue gray glass
It is often used for elegant cover plates for heaters (indoors/outdoors) but also for decorative elements.
NEXTREMA® opaque gray (712-8)
Of all the NEXTREMA variants, opaque gray glass stands out for its thermal insulation, which is by far the best, thanks to its low transmission in the infrared spectrum. This opaque glass blocks visible light. It also has high heat resistance, up to 950°C.
This opaque gray glass ceramic is also robust against acids, bases and corrosion.
The use of Nextrema opaque gray glass
This type of glass is very often used for interior linings of ovens in high temperature clean rooms, cover plates, decorative cover plates etc.
