New applications for Sc: zero thermal expansion materialAustralian researchers have created what may be one of the most thermally stable materials ever discovered. This new zero thermal expansion (ZTE) material made of scandium, aluminum, tungsten and oxygen did not change in volume at temperatures ranging from 4 to 1,400 Kelvin (-269 to 1126 °C, -452 to 2059 °F).
That's a wider range of temperatures, say scientists from the University of New South Wales (UNSW), than any other material demonstrated to date, and it could make orthorhombic Sc1.5Al0.5W3O12 a very handy tool for anyone engineering something that needs to work in extremely varied thermal environments.
