Microstructures and mechanical properties of dense particle gels: Microstructural characterisation

Schenker, Iwan; Filser, Frank T; Aste, Tomaso; Gauckler, Ludwig J

Description

The macroscopic mechanical properties of wet ceramic green bodies and densely packed coagulated colloidal particle gels strongly depend on the local arrangement of the powder particles on length scales of a few particle diameters. Heterogeneous microstructures exhibit up to one order of magnitude higher elastic properties and yield strengths than their homogeneous counterparts. The microstructures of these gels are analysed by the "straight path" method quantifying quasi-linear arrangements of...[Show more]
