Abstract
A matrix composed of polyvinyl-alcohol (PVA) mixed with different concentration ratios of the granular strontium chloride (SrCl(2)center dot 6H(2)O) were prepared by casting technique method at room temperature (about 30 degrees C). The electric and dielectric properties such as a.c. electrical conductivity by a conventional method, using Keithly 616 digital electrometer, dielectric constant, and dielectric loss were measured. Calculated equilibrium properties such as lattice constant, bulk modulus and elastic constants are in good agreement with experimental results. The calculated activation energy values agree well with experiment only when the SrCO(2) molecules are allowed to displace under strain, indicating the importance of inner strain relaxation. From the elastic constants, theoretical values of the Young's modulus, shear modulus, Poisson's ratio, of SrCl(2) are obtained. In addition mechanical properties such as Young's modulus, creep relaxation, and energy stored properties for these samples were also determined at room temperature.
