In other materials that show negative thermal expansion, the vibrational modes that pull the solid together create instabilities that eventually lead to rearrangements in the atomic structure.

Thermal Expansion Coefficient A thermal expansion coefficient is a well-established key principle that all solid materials have different properties when exposed to variations in temperature.

What Thermal Properties Does TMA Give Information About? Softening, crystallization, anisotropy, solid–solid transitions, creep and stress relaxation, glass transition temperature (Tg), coefficient of ...

Specialists have estimated that the Eiffel Tower actually grows between 12 and 15 centimetres when comparing its size on cold ...

But some solid crystals, like scandium fluoride, shrink when heated — a phenomenon called negative thermal expansion.

Most solids expand when heated, a familiar phenomenon with many practical implications. Among the rare exceptions to this rule, the compound zirconium tungstate stands out by virtue of the enormous ...
