This article gives a description of a modification of the standard Brunaner-Emmett-Teller (BET) method for the determination of the surface area of metal powders. The modified procedure involves the use of CO2 as adsorbate, the determination of adsorption isotherm from three measured points and other simplifications. The use of CO2 for tungsten and molybdenum powders seems to give just as satisfactory results as in the case of conventional N2. It is shown that values within 2% of those by the standard method using CO2 are obtained by this simplified procedure One sample can be measured in about 1.5 hr with the result reproducible within 2%.
