Tswiza Ball Milling Of Zrb2 Powder Reviews

Oxide impurities in ZrB 2 powders promote coarsening, resulting in lower sinterability. Given its importance for sintering, we studied the oxidation of ZrB 2 powders during highenergy ballmilling the form of milling able to refine ZrB 2 powders to the nanoscale with the aid of various characterization techniques, namely fusion in inert gas, Xray diffractometry, helium pycnometry
