Also intriguing high-technology manufacturers are thin ceramic sheets.
Corning developed ceramic sheets made with zirconia more than a decade ago for use in fuel cells, electronics, gas sensors, and other applications。 Leveraging our deep understanding of ceramic engineering and modeling, Corning recently developed a revolutionary roll-to-roll (R2R) ceramic processing method to manufacture Ribbon Ceramics – high quality, fully dense ceramic substrates in ribbon or wafer format。
Ribbon Ceramic made from zirconia comes in thicknesses as low as 20 microns。 It has attracted attention over recent years for its potential use in microbatteries for smartcards, sensors, and Internet-connect wearables。
More recently, Corning began exploring an alumina version of Ribbon Ceramic with high thermal conductivity. Alumina Ribbon Ceramic is ideal for use in LED lighting, power electronics, and radio frequency applications.
Flexible ceramics also offer potential for more economical production of solid-state batteries. Thin, long-lasting ceramic electrolytes, produced via roll-to-roll manufacturing, offer an alternative to the liquid electrolytes widely used in today’s shorter-lived rechargeable lithium ion batteries.
While glass and ceramics draw their compositions from different elements, Corning researchers are finding more and more parallels between the way the materials behave in ultra-thin, flexible form factors。 The materials are helping give rise to other industry innovations, too, like new methods of coating rolled surfaces -- just one more example of growing commercial potential for roll-to-roll processing。
