Cryo Milling | Material Milling | AVEKA

Water-sensitive materials can be cryo-milled because when liquid nitrogen expands from its liquid state to its gaseous state, its volume increases 694 times. This is enough to quickly exclude any other gas, including water vapor, from being in the atmosphere of the mill, as long as the liquid nitrogen …
