Powder form and BET surface: an in-depth exploration of characterisation

Powdered materials play a crucial role in the world of materials science, ranging from pharmaceuticals to catalysts and building materials. The characterisation of these powders is essential for understanding their properties and applications. An important technique used to characterise the surface of powders is the BET method. Let us dive into the meaning of powder form and the role of BET surface in their characterisation.

Powder: the building blocks of various industries

Powdered materials consist of small particles that move freely in space. These particles can vary in size, shape and composition, giving them a wide range of properties and applications. From fine powders used in cosmetics to coarser powders used in building materials, the diversity is enormous. The properties of powders are influenced by factors such as particle size, morphology and surface area.

BET surface: a measure of active surface

The BET method, developed by Brunauer, Emmett and Teller, is an important technique for measuring the specific BET surface area of materials, including powders. This method is based on the physical adsorption of gas molecules on the surface of the material. By measuring the amount of gas molecules absorbed at different pressures, the surface area can be calculated according to the BET equation. The specific surface area is a crucial parameter that affects the reactive sites and the degree of interaction with other materials, which is essential for many applications, such as catalysis, adsorption and separation processes.
