Investigation of oxidation process of mechanically activated ultrafine iron powders [PDF]
, 2008 The oxidation of mechanically activated ultrafine iron powders was studied using X-ray powder diffraction and thermogravimetric analyzes. The powders with average particles size of 100 nm were made by the electric explosion of wire, and were subjected to

Properties and Performance of Tricalcium Silicate Milled in a Planetary Ball Mill
Acta Physica Polonica A, 2014 The focus in this study is on the e ect of high energy milling on tricalcium silicate, the main constituent of ordinary Portland cement. Changes in the performance, e.g. hydration heat release, due to milling in a planetary ball mill (Pulverisette 5, Fritsch, Germany) were observed. For comparison, carefully milled tricalcium silicate was produced with
