A Note on the Permeability of Refractory Materials to Gases

JSGT 1933 V17 T093-T101

Measurements of the porosities and of the permeabilities of refractories to gases axe reported; it is shown that porosity measurements offer no guide to permeability except under such special circumstances as are not likely to occur in commercial usage. An apparatus is described which enables measurements of permeability to be made at elevated temperatures. The influence of temperature on permeability has been measured in the case of some experimental refractories.
