ABSTRACT:
A method of making high-purity fine particles of reactive metals, reactive especially in terms of their inclination to form hydroxides, comprises the steps of: preparing an inert gas atmosphere within which to manufacture the particles; reducing the moisture remaining in the inert gas atmosphere to an extremely low level; pulverizing the reactive metal within the moisture-free inert gas atmosphere; and collecting and sealing the product particles of reactive metal in a storage container in the same moisture-free inert gas atmosphere. The vessel for containing the inert gas atmosphere comprises: a hermetically sealable vessel capable of maintaining the inert gas atmosphere; a pair of rubber gloves for carrying out manual operations in the vessel under the inert gas atmosphere; a cryogenic cooling device attached to one wall of the vessel for condensing away the moisture remaining in the inert gas atmosphere into dew droplets; and an accumulator for equalizing the inner pressure of the vessel with the ambient atmospheric pressure.
