『Abstract
Specific surface area measurements of The Clay Minerals Society
source clays were made by the Brunauer, Emmett and Teller (BET)
method of adsorption of nitrogen gas. Two replicate measurements
of specific surface area were performed for each source clay.
All pair values were within 3％, which is very good agreement for
this type of measurement.
Keywords: BET; Hectorite; Kaolinite; Montmorillonite; Palygorskite;
Source clays; Specific surface area』
