Data classification with the Vogel Fulcher Tammann Hesse viscosity equation using correspondence analysis
(2007)
The well-known Vogel-Fulcher-Tammann-Hesse equation (VFTH, log10 eta = A+B/(T-T0), eta in Pa.s and T in K) has been extensively used in the description & characterization of cooperative molecular motion by means of the ...
Kinetics and mechanisms of crystal growth and diffusion in a glass-forming liquid
(2004-11)
Extensive data on the viscosity, covering 15 orders of magnitude, and crystal growth rate, covering seven orders of magnitude, of liquid diopside (CaO.MgO.2SiO(2)) were collected in a wide range of undercoolings from ...
Viscosity of strong and fragile glass-forming liquids investigated by means of principal component analysis
(2007-01-01)
The Vogel-Fulcher-Tammann-Hesse (VFTH) equation has been the most widespread tool for describing the temperature dependence with viscosity for strong, moderate and fragile glass-forming liquids. In this work the VFTH ...
Diffusion coefficients for crystal nucleation and growth in deeply undercooled glass-forming liquids
(2007-01-01)
We calculate, employing the classical theory of nucleation and growth, the effective diffusion coefficients controlling crystal nucleation of nano-size clusters and the subsequent growth of micron-size crystals at very ...
Structural and dielectric properties of relaxor Sr0.5Ba 0.5Bi2Nb2O9 ceramic
(2010-03-01)
Sr0.5Ba0.5Bi2Nb2O 9 ceramic was prepared by a conventional solid state reaction method and studied using X-ray powder diffraction and dielectric measurements. At room temperature, an orthorhombic structure was confirmed ...
