Measurement of the specific surface of metal powders in the laboratory

You want to measure the specific surface of your metal powders

Why measure the specific surface of your metal powders?

Firstly, the specific surface area of a powder is the sum of the specific surface areas of the grains that make it up. The surface area of a grain refers to its real surface area as opposed to its apparent surface area. It represents the total surface area per unit mass and is expressed in m²/g.

Of the methods for measuring specific surface area, the gas adsorption determination described by Brunauer, Emmett and Teller, known as the BET method, is by far the most important and widely used.

The specific surface measurement consists of determining the amount of gas required to form a mono-molecular layer around the solid sample. As the cross-sectional area of the molecules is a specific characteristic for each gas, it is possible to determine the total surface area of the solid.

The specific surface area is one of the physico-chemical properties that must be measured during a metal powder characterisation process.

Thus, the support of a laboratory competent in the measurement of specific surface is essential to answer your problems of characterization of metallic powders.
