The effect of extra framework species on the intrinsic negative thermal expansion property of zeolites with the LTA topology.
نویسندگان
چکیده
X-Ray powder diffraction studies have been used to measure the thermal expansion properties of three zeolites with the LTA topology and provide details of the underlying structural changes. Siliceous ITQ-29 and dehydrated and hydrated silver zeolite A have large negative, moderate negative and positive thermal expansion coefficients, respectively.

Thermal behaviour of zeolites is an important property regarding their application in different fields. This property mainly is related to the presence of water molecules in their crystalline structures. It is known that zeolites give up water molecules upon heat ing, a phenomena which affects remaining water molecules and other clements in the framework. This effect mainly depends on the...
متن کاملEffects of nonframework metal cations and phonon scattering mechanisms on the thermal transport properties of polycrystalline zeolite LTA films
We present a systematic study to investigate the effects of nonframework cations and the role of phonon scattering mechanisms on the thermal transport properties of zeolite LTA, via experiment and semiempirical lattice dynamics calculations. Our study is motivated by the increasing interest in accurate measurements and mechanistic understanding of the thermal transport properties of zeolite mat...
متن کاملNormal mode approach for predicting the mechanical properties of solids from first principles: Application to compressibility and thermal expansion of zeolites
We present a method for analyzing the mechanical properties of solids, based on normal modes and their coupling to lattice strains. This method was used to study elastic compression and thermal expansion of zeolites, with parameters calculated from density functional theory. We find in general that the bulk modulus can be divided into two contributions: a positive term arising from compression ...
متن کاملMediating role of intrinsic work motivation in relationship between job commitment and professional ethics with firefighters' extra-role performance
Background: A firefighting job is a demanding job that has a high degree of stress due to constant exposure to life-threatening conditions. Therefore, the present study was conducted to investigate the mediating role of intrinsic job motivation in the relationship between job commitment and professional ethics with extra-role performance among firefighters in Isfahan. Methods: The type of stud...
متن کاملFramework stabilization of Si-rich LTA zeolite prepared in organic-free media.
Zeolite HOU-2 (LTA type) is prepared with the highest silica content (Si/Al = 2.1) reported for Na-LTA zeolites without the use of an organic structure-directing agent. The rational design of Si-rich zeolites has the potential to improve their thermal stability for applications in catalysis, gas storage, and selective separations.
