Most metals expand when their temperature rises. The Eiffel Tower, for example, is about 10 to 15 centimeters taller in ...

Hot material The crystal structure of cordierite gives the material its unique thermal properties. (Courtesy: M Dove and L Li/Matter) The anomalous and ultra-low thermal expansion of cordierite ...

Unlike most materials, cordierite displays an unusual combination of thermal expansions: low positive expansion along two perpendicular axes and negative expansion along the third. This unique ...
