The specific surface of a material or (VSSA: volume specific surface area) designates its real surface as opposed to its apparent surface.
It represents the total surface per unit of mass and is expressed in m²/g.
The most widespread technique for the measurement of the VSSA is the BET method.
FILAB has significant experience in the measurement of specific surface area and can provide you with the support of its teams and its design office.
The volume of the specific surface may be necessary for the following expertises:
