1. EFFECTIVE ELASTIC CONSTANTS OF PLAGIOCLASE FELDSPAR AGGREGATES IN DEPENDENCE OF THE ANORTHITE CONTENT - A CONCISE REVIEW

Author

Willi Pabst, Eva Gregorova, Rambaldi Elisa, and Bignozzi Maria Chiara

Subjects
Albite, Oligoclase, Andesine, Labradorite, Bytownite, Anorthite, Young modulus (Tensile modulus), Poisson ratio, Shear modulus, Bulk modulus (Compressive modulus), Elasticity, Geophysics, Seismology, Rock-forming minerals, Wollastonite, Feldspar, Ceramic tiles, Ultrasonic velocity, Adiabatic elastic constants, Simulation (Density functional theory), Impulsive stimulated light scattering, Review, Clay industries. Ceramics. Glass, TP785-869
Abstract

Recent work on the elastic constants of plagioclase feldspars is reviewed. Based on the 21 elastic constants (stiffnesses) reported in the literature for triclinic plagioclase monocrystals of different composition, the effective elastic constants of dense, single-phase, polycrystalline plagioclase aggregates with isotropic microstructure are calculated via standard VoigtReuss-Hill averaging. Master curves show the good agreement of the constants obtained via the two approaches (experiment and simulation) and recall the fact that values reported in the older literature have been underestimated. Fit relations are given for the calculation of Young modulus, shear modulus, bulk modulus, Poisson ratio and density in dependence of the composition. These fit relations may serve as handy tools for obtaining relevant input information for the calculation of effective elastic constants of multiphase ceramics produced with Ca and Na containing raw materials.

Based on the 21 elastic constants (stiffnesses) reported in the literature for triclinic plagioclase monocrystals of different composition, the effective elastic constants of dense, single-phase, polycrystalline plagioclase aggregates with isotropic microstructure are calculated via standard Voigt- Reuss-Hill averaging. Master curves show the good agreement of the constants obtained via the two approaches (experiment and simulation) and recall the fact that values reported in the older literature have been underestimated. Fit relations are given for the calculation of Young's modulus, shear modulus, bulk modulus, Poisson ratio and density in dependence of the composition. These fit relations may serve as handy tools for obtaining relevant input information for the calculation of effective elastic constants of multiphase ceramics produced with Ca and Na containing raw materials.
