    Powierzchnia właściwa proszków, porównanie wyników policzonych i zmierzonych metodami przepływowymi i adsorpcyjnymi
    (2006) Kordek, Jacek; Gawenda, Tomasz; Kępys, Waldemar
    For some powders of mineral origin, the precise grain composition and specific surface determination was done. The compositions were determined by two laser methods and specific surface by Blaine's flowing method of and adsorptive method BET. The juxtaposition of results given in such way allow to formulate an opinion about the term »specific surface« because of totally different approach to results and their significantly different values. The conducting of parallel measurements confirms that physical and chemical, as well calculating determinations spare to various purposes may be comparable when the right proposed rules are applied.
