Determination of the monoclinic, tetragonal and cubic phases in mechanically alloyed ZrO2-Y2O3 and ZrO2-CoO powder mixtures by Raman spectroscopy

In the paper is shown that Raman spectroscopy is very suitable method for distinguishing polymorphic structures existing in various ZrO2-based samples which were prepared from powder mixtures by high-energy ball milling (mechanical alloying) technique.
