ominaispintaalan
Ominaispintaala, often translated as specific surface area, is a physical property of a material that quantifies the total surface area exposed per unit of mass or volume. It is typically expressed in units of square meters per gram (m²/g) or square meters per cubic meter (m³/m³). This property is particularly relevant for porous materials, powders, and finely divided substances where the internal surface area can significantly exceed the external geometrical surface area.
The measurement of ominaispintaala is crucial in various scientific and industrial applications. For instance, in catalysis,
Common methods for determining ominaispintaala include gas adsorption techniques, such as the Brunauer-Emmett-Teller (BET) method, which
