Is the ball milling of zinc powder has to be operated with the protection of inert atmosphere and/or continuous cooling for both safety and oxidation problems?
The easiest way to grind zinc with kerosene. Kerosene protects against oxidation and cools the grist. In addition, wet milling is always more efficient than dry milling.
Thank you Vadim Verlotski , is kerosene itself a flammable liquid? is it the solvent absorbs the heat generated, cooling down the temperature inside the vial?
Liquids when grinding distribute the heat evenly throughout the entire volume of the mill, so kerosene remains relatively cold (max. 40-50°C) and it is well below its evaporation temperature. For this reason, kerosene is used for milling of metals and not other, easily evaporating, organic liquids such as gasoline, ethanol or acetone.
