摘要：

Strong isotropic negative thermal expansion (alpha = -4.2 x 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.
