Fly Ash Cenospheres : Composition , Morphology , Structure , and Helium Permeability

The interrelation between the composition, morphology, structure, and helium permeability of the shells of narrow fractions of nonmagnetic non-perforated cenospheres has been investigated. The narrow fractions of nonmagnetic nonperforated cenospheres have been separated from concentrates of cenospheres of the sialic fly ash type with the use of the… CONTINUE READING
