Porosity is a fundamental property of materials that describes the presence of voids or pores within them. These pores can be interconnected or isolated and can vary significantly in size, shape, and distribution. The total volume of these pores relative to the total volume of the material is quantified as porosity, often expressed as a percentage or a fraction. Porosity is a key characteristic that influences a wide range of material properties and behaviors.

In geological contexts, porosity is crucial for understanding fluid flow and storage within rocks and soils. For example, aquifers, which are underground layers of permeable rock or sediment, rely on high porosity and interconnected pores to hold and transmit groundwater. Similarly, the presence of pores in rocks can affect their seismic wave propagation, density, and susceptibility to weathering.

Beyond geology, porosity is vital in materials science and engineering. In ceramics, porosity can impact strength, thermal insulation, and filtration capabilities. For engineered porous materials like sponges or foams, the controlled creation of specific pore structures is essential for their intended functions, such as absorption, cushioning, or catalysis. The study of porosity, often referred to as porometry, employs various techniques to measure and characterize pore networks, providing insights into material performance and enabling the design of materials with tailored properties.
