Characterisation of porosity in zirconia-based nanopowders

Prochazka, I.; Cizek, J. A.; Melikhova, O.; Hruska, P.; Anwand, W.; Konstantinova, T. E.; Danilenko, I. A.


Porosity in several zirconia-based pressure compacted nanopowders was studied using the positron lifetime technique combined with the mass-density measurements. Two kinds of pores were identified: (i) the larger pores of. 10 to 19 nm diameter arising likely from a formation of secondary particle aggregates, and (ii) the smaller ones (. 1 nm) which are obviously of a more complex origin
