GB/T 6609.35-2023 specifies a method for determining the specific surface area of alumina powder using the nitrogen adsorption method (typically based on the BET principle). This method involves measuring the amount of nitrogen adsorbed by an alumina sample at liquid nitrogen temperature, from which the total specific surface area is calculated. This parameter is crucial for characterizing the surface properties of alumina.
