El area superficial especifica divide la superficie total por la masa y se usa para polvos y solidos porosos.

Formula clave

SSA = S / m
Spherical estimate: SSA approx 6 / (ρ x d)
BET: gas adsorption is used to estimate monolayer surface coverage.

Ejemplo practico

Example: if S = 12 m2 and m = 4 g, SSA = 12 / 4 = 3 m2/g.
Nota importante: BET values are laboratory measurements. Geometric formulas are only rough estimates for non-porous particles.
