Negative Thermal Expansion
Introduction Many materials which we encounter in everyday life expand on heating. This fact of life is easily highlighted with a simple experiment that we are all familiar with and involves a metallic sphere passing through a metal ring. At room temperature, the sphere is of such a size that it can easily pass through the ring, but after the sphere is heated, it will have expanded with the res...
متن کاملNegative Thermal Expansion in Ba0.5Sr0.5Zn2SiGeO7
Solid solutions with the composition Ba0.5Sr0.5Zn₂Si2-xGexO₇ and BaZn₂Si2-xGexO₇ were prepared with different values of x using a conventional mixed oxide route. Both compounds exhibit very different thermal expansion, which is due to the different crystal structures. Ba0.5Sr0.5Zn₂Si2-xGexO₇ solid solutions exhibit the structure of high-temperature BaZn₂Si₂O₇ and show negative thermal expansion...
متن کاملNegative thermal expansion in beta-quartz
M.T. Dove ()) Dept. of Earth Sciences, University of Cambridge, Downing Street, Cambridge CB2 3EQ, UK Abstract Computer modelling and theoretical analysis are used to explain the nearly zero and slightly negative coefficients of thermal expansion in b-quartz well above the a-b phase transition temperature. Quartz was selected for study as an archetypal material with a framework structure of sti...
متن کاملSoft manifold dynamics behind negative thermal expansion.
Minimal models are developed to examine the origin of large negative thermal expansion in underconstrained systems. The dynamics of these models reveals how underconstraint can organize a thermodynamically extensive manifold of low-energy modes which not only drives negative thermal expansion but extends across the Brillioun zone. Mixing of twist and translation in the eigenvectors of these mod...
متن کاملSolid state sintering of very low and negative thermal expansion ceramics by Spark Plasma
Lithium aluminosilicate powder precursors of compositions Li2O:Al2O3:SiO2 as 1:1:2; and 1:1:3.11 were synthesized and sintered by the Spark Plasma Sintering technique. The sintering conditions were adjusted to obtain dense ceramic materials in an attempt to avoid the presence of a glassy phase. XRD and SEM images were employed for composition and microstructure characterization. The coefficient...
