  • Process for preparation of granules of low-melting-point metals
    Patent number: 4450885
    Abstract: A process for the preparation of granules of low-melting-point metals which comprises spouting a melt of a low-melting-point metal in the form of fine streams in a gas phase under melt fracture-causing conditions and introducing the fine streams of the molten metal into a collecting liquid phase so that the speed of the molten metal fine streams just above the liquid face is 50 to 300 cm/sec is disclosed.
