New Materials, Applications, and Research Excite the Specialty Glass Market

The coming years are set to be an exciting time in glass-ceramics. Companies have returned to pre-crash levels of financial health, and they have begun making healthy investments in research and development to lay the groundwork for their futures.


Glass-ceramics are fueling this research, as science and industry turn to this material for its unique blend of optical, mechanical, physical and chemically resistant properties, along with its six-decades history of meeting the challenges of demanding applications.

SCHOTT is helping to build on that history, working with researchers to solve technical challenges in various industries that require new material formulations, coatings and processing methods.

As a leading expert in specialty glass, SCHOTT’s passion is to research and discover new possibilities with glass and materials for advanced technologies. The company contributes to its customers’ success and collaborates to propel research.

NEXTREMA demonstrates what makes glass-ceramic a unique, groundbreaking solution. Its exceptional technical properties offer engineers and designers a toolbox with which they can forge new applications. This high-performance glass-ceramic withstands temperatures of 950°C, and has near-zero thermal expansion.

CERAN glass-ceramic offers unmatched durability and performance in cooktops, and ZERODUR has been the standard material for mirror substrates in astronomical telescopes for almost 50 years, providing extremely high-resolution images from space due to its practically zero coefficient of thermal expansion.

Glass bends for pneumatic conveying systems are another area of application. The transparency of the glass ensures simple monitoring of the material flowing through, and a wide range of diameters with various bend angles ensure an accurate match to existing conveying systems.

SCHOTT manufactures 60 different types of tubes, of varying diameters and wall thicknesses, with additional coatings to expand the number of applications. The company can process tubing with specific light transmittance properties, better infrared transparency, and higher shock and chemical resistance, and match the coefficients of expansion of materials like tungsten, Kovar or other ceramics for glass-to-metal seals.

DURAN tubing, for example, can be used to build photobioreactors that grow algae. Museums surround their finest artifacts with DURAN coated in anti-fingerprint and anti-reflective coatings that have a tunable spectral range for maximum transparency.

The market for glass-ceramic and specialty glass is healthy, and SCHOTT is seeing growth through targeted development of existing glass products and establishing innovative products in new markets.
