Fit for Extreme Conditions

The high-tech glass-ceramics from the NEXTREMA™ brand family open up new areas of application for engineers and designers, particularly in high temperature environments of between 400 and 950 degrees Celsius.

The impressive range of their properties and exciting conceivable applications guarantee a bright future for these glass-ceramics,” notes the well-known Brazilian glass-ceramic expert and university professor Edgar Dutra Zanotto. His assessment met with broad approval at the scientific colloquium SCHOTT held on glass-ceramics in 2011. Now, this material of the future is ready to show how much potential it actually holds: SCHOTT launched a new portfolio of high-performance glass-ceramics in 2012. Their brand name NEXTREMA™ is derived from ”Next Extreme Material” which powerfully expresses the direction that this development is moving in. Thanks to its unique technical properties, this high-performance material will open up new areas of application in which conventional materials like plastics, glass and metal meet their limits.

In the construction of technical applications, engineers and material experts rely heavily on the physical, chemical and mechanical parameters of materials. Robustness under extreme temperature loads and high chemical resistance are often important parameters. At the same time, designers are looking for high-tech materials in the most varied colors, shapes and appearances to create innovative products with a modern industrial design. “NEXTREMA™ gives new impetus for both approaches,” explains Michael Glaninger, the responsible product manager at SCHOTT.

”NEXTREMA™ is not just a product that can be used in a specific application, but rather a family of materials for use in realizing future ideas that we intend to develop together with interested partners,” he adds.

Here, it is important that the technical properties stand up well in various industries. The glass-ceramics can be put to use at temperatures of up to 950 degrees Celsius, as an inner lining or substrate material in high temperature processes used in semiconductor technology, for example. When it comes to manufacturing displays, chips and wafers for the semiconductor market more efficiently, they can leverage their product char-acteristics such as temperature stability, chemical inertness for coating processes and a broad optical transmission spectrum. At the same time, however, opportunities are also opening up in the electrical industry, medical technology or home appliance industry, for instance as an efficient substrate that resists severe changes in temperature for use in coating heating elements in small electronic devices.

Furthermore, NEXTREMA™ also opens up unique new design possibilities. ”We are thinking about how white glass-ceramics can be used to produce attractive housing components for modern electronic appliances, for instance,” Glaninger says. “There are so many application possibilities. NEXTREMA™ is a special material that offers extreme properties which we intend to take to the limit in order to come up with innovations. In this regard, continued technical development and an attractive product design obviously go hand in hand. We are looking forward to taking part in fruitful exchanges with interested customers,” he concludes. <|
