METODO MEJORADO PARA LA PRODUCCION DE GRANULOS DE METALES DE BAJO PUNTO DE FUSION,SELECCIONADOS ENTRE PLOMO,CADMIO,ESTANO Y ZINC

摘要

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. According to this process, granules having a substantially spherical shape and being uniform in the size can be prepared very easily at high efficiency.
