volumeverlies
Volumeverlies is a term used in materials science to describe irreversible volume loss that a material experiences under processing or service conditions. It represents a permanent reduction in solid volume caused by mechanisms such as compaction, sintering, desorption of fluids, phase changes, or chemical degradation, and is distinguished from reversible thermal expansion or elastic deformation.
The word is a simple portmanteau of volume and loss. It has no universally established definition and
Applications and contexts include porous materials, soils, foams, catalyst supports, and battery electrodes, where processing steps
Measurement and reporting typically use the relative volume change, ΔV/V0, expressed as a percentage or fraction.
Volumeverlies relates to but is distinct from related concepts such as shrinkage, densification, compaction, and aging.
