Strong negative thermal expansion in siliceous faujasite

Abstract

Strong isotropic negative thermal expansion (α = –4.2 × 10^–6 K^–1) found for siliceous faujasite over a temperature range of 25 to 573 K is attributed to transverse vibrations of the bridging oxygen atoms, a model supported by structural refinements of X-ray diffraction data as a function of temperature.
