Exfoliated vermiculite is a porous silicate material well known for its broad applications in insulation and horticulture. The particles of exfoliated vermiculite have a range of unique properties, such as being lightweight, soft, chemically stable, and compressible. Unlike general silicate materials, exfoliated vermiculite displays an exceptional plasticity combining with a brittle deformation under compressive and/or shear forces, which effectively absorbs mechanical energy under an impact. Per microstructural investigations, this study demonstrated the deformation process of exfoliated vermiculite particles. The deforming mechanisms were accordingly discussed.
