Calibration of a fisher air-permeability apparatus for determining specific surface

The Analyst, 1966
Calibrating the Fisher sub-sieve sizer at a single particle-size level does not ensure accuracy at other levels unless several variables are controlled. Instrument modification that give better control of the several variables, and a calibration method that ensures accurate air-flow measurement without depending on a particle-size standard, are ...

The specific surface of powders. A modification of the theory of the air‐permeability method

Journal of the Society of Chemical Industry, 1947
AbstractThe paper describes a modification of the Kozeny theory of the air‐permeability method for determining the specific surface of powders to take into account the effect of “slip” at the walls of the pores in the bed of powder. The dependence of the measured value of specific surface on the mean pressure in the bed has been examined experimentally,

Measurement of the specific surface area of fine powders. A comparison of the ‘gas‐adsorption’ and ‘air‐permeability’ methods

Journal of Applied Chemistry, 1957
AbstractMeasurements of specific surface areas of nineteen powders of various chemical and physical types have been made (a) by adsorption of nitrogen on to the powders at 77° K and (b) by the air‐permeability method described by Rigden.The results obtained by the two methods were appreciably different, the areas obtained by the adsorption method being
