锂皂石有机改性后,吸附性能、分散性及比表面积等提高。
The value of oil absorption, viscosity of Nujol mull, specific surface area, contact angle, distribution of particle size and dispersivity of the calcium carbonate particles were also characterized.
Specific surface area (SSA) is a property of solids defined as the total surface area of a material per unit of mass, (with units of m²/kg or m²/g) or solid or bulk volume (units of m²/m³ or m).
It is a derived scientific value that can be used to determine the type and properties of a material (e.g. soil or snow). It has a particular importance for adsorption, heterogeneous catalysis, and reactions on surfaces.
