RELATIONSHIP BETWEEN THE SPECIFIC SURFACE AREA …
the specific surface area of samples with a high specific surface area because they had a porous inner structure. In contrast, the values obtained for these samples using the BET technique exhibited a good correlation with the certified values (Table 1). It was subsequently evaluated for which materials there was a satisfactory correlation
