POSSIBILITIES OF THE WEAR CONTAMINATION DECREASING OF THE MILLED SILICON POWDER |
Abstract
In this work are presented the possibilities of minimisation of contamination contents by convenient milling procedure and chemical purification of milled powders. A combined procedure of long-term dry milling with consequent short-term disaggregative re-milling in adsorption active solvating environment is more advantageous from the view of the powder purity and wear of milling balls in comparison with the long-term milling in liquid environment. There is recommended to use steel milling balls for the preparation of ultrafine powders because of easy purification of iron wear by chemical methods.
