Specific Surface Area

Marija Šljivić-IvanovićIvana Smičiklas, in Advances in Construction and Demolition Waste Recycling, 2020. 23.3.3 Specific surface area.

General Chapters: <846> SPECIFIC SURFACE AREA

2014-9-5 · INTRODUCTION. The specific surface area of a powder is determined by physical adsorption of a gas on the surface of the solid and by calculating the amount of adsorbate gas corresponding to a monomolecular layer on the surface. Physical adsorption results from relatively weak forces (van der Waals forces) between the adsorbate gas molecules and ...

Surface area

Surface area is commonly measured by the adsorption of an inert gas on a solid surface. It is commonly expressed as specific surface area, which is the surface area per unit weight of the powder. Adsorption of an inert gas (the adsorbate) on a solid surface (the adsor-bent) is driven by the weak van der Waals forces of attraction.

Specific Surface Area of Blue Tungsten Oxide

2018-3-8 · The specific surface area of tungsten oxide is the total surface area per unit mass tungsten oxide powder. It is commonly expressed by m 2 /g. It indirectly reflects the particle size and particle morphology of tungsten oxide powder, and it is an important index to measure the reaction ability of tungsten oxide powder with gas solid material during the reduction process.
