Abstract
The elastic properties of ceramics and a mix of minerals can be calculated in a simple way including some properties of the interfaces between grains. While the Hashin Shtrikman averaging method has bounds, which are strictly correct for many realistic physical conditions, one fi nds empirical data which lie outside these bonds. One possible interpretation is that the scaling of the volume proportions in mineral assemblies is not truly represented by the nominal volume proportion f of each phase. It is argued that interfacial effects scale with f(1–f). In the case of certain assemblies, it is shown that the scaling is entirely with f2 rather than f. For intermediate cases, a more realistic scaling replaces f in the relevant averaging schemes by f(1–S) + S f2 where S weighs the effect of the non-linearities in the volume expansion of the averaging schemes.
