fe nanopowders ball milling

Ball Milling method for synthesis of nanomaterials Jun 15, 2012 Ball Milling method for synthesis of nanomaterials. Advantages of ball milling process: 1. Nanopowders of 2 to 20 nm in size can be produced. The size of nanopowder also depends upon the speed of found that two various phases of Fe-Si solid solution with Curie temperatures 749oC and 715oC can be formed by ball milling of Fe-Si (6,5 wt.% of Si) at room temperature. The Curie temperature of the Fe-Si (6.at%. of Si) solid solution is 749 oC and the Curie

Milling Cutters

Choose from our selection of end mills and milling cutters, arbor-mount milling cutters, end mill and milling cutter sets, and more. In stock and ready to ship.
