specific surface area

The value obtained for specific surface area depends upon the method of measurement.

For instance, grinding a sample to a higher specific surface area increases its reactivity.

The surface area in relation to the mass of a sphere is called the specific surface area.

The average specific surface area of Pd/Fe particles is about 35 m/g.

Activated carbon properties are determined by its porosity, the specific surface area, texture characteristics.

Prolongued grinding results in an increased pozzolanic activity by creating a larger specific surface area available for reaction.

Based on the very high specific surface area of aluminium those platelets instantaneously oxidize upon contact with air.

Clay minerals typically have specific surface areas in the range of 10 to 1,000 square meters per gram of solid.

This depends upon a relationship between the specific surface area and the resistance to gas-flow of a porous bed of powder.

The rate of initial reaction (up to 24 hours) of the cement on addition of water is directly proportional to the specific surface area.

For nanopowder to determine the specific surface area the B.E.T. method is commonly used.

The total amount of water held when field capacity is reached is a function of the specific surface area of the soil particles.

Due to its high specific surface area and its unbalanced negative charges, clay is the most active mineral component of soil.

This arises from the large specific surface area and differences in surface atomic structure of nanoparticles at small particle sizes.

Because cement particles react with water at their surface, the specific surface area is directly related to the cement's initial reactivity.

Generally magnesium powder having a high specific surface area will exhibit a higher burn rate than those having a smaller specific area.

Silt is mineralogically like sand but with its higher specific surface area it is more chemically active than sand.

They exhibit permanent porosity with specific surface areas surpassing those of well-known zeolites and porous silicates.

However, it should be noted that although the reduction of particle size increases the specific surface area and the dissolution rate, it does not affect solubility.

Among carbon materials, microporous CDCs exhibit some of the highest reported specific surface areas (up to more than 3000 m/g).

Moreover, the filamentation benefits bacterial cells attaching to a surface because it increases specific surface area in direct contact with the solid medium.

The specific surface area of silica fume can be measured with the BET method or nitrogen adsorption method.

Activated charcoal is an electrical conductor that is extremely porous "spongy" form of carbon with a high specific surface area, providing a useful electrode material.

The unique property of gas-liquid foams having very high specific surface area are exploited in the chemical processes of froth flotation and foam fractionation.
