Abstract

PURPOSE:To simply produce fine particles of gallium-contg. metal at a low cost by cooling molten gallium-contg. metal by spouting into an aq. soln. as a cooling medium in an inert gaseous atmosphere. CONSTITUTION:An alloy of gallium with a metal selected among the groups II, III and IV elements of he periodic table such as indium, zinc, tin and aluminum or only metallic gallium is melted. This molten gallium-contg. metal is cooled by spouting from an injecting nozzle into an inert gaseous atmosphere and dropping into an aq. soln. as a cooling medium. It may be cooled by direct spouting into the aq. soln.

(b) Background Art Various methods for producing metal powders such as gold, silver, copper, zinc, iron, etc., especially powders of metals or their alloys for powder metallurgy, have been proposed and industrialized. There is no technology related to a method for producing fine particles of gallium alloy, and it has conventionally been thought that it is impossible to produce fine powder of metallic gallium or gallium alloy.

その理由としては、まずガリウムは金属としては水銀、

微粉末製造に適さないことが上げられる。
The reason for this is that gallium, as a metal, is mercury,
It has the third lowest melting point after cesium (melting point 29.78
For example, the melting point of gallium-indium (76:24) alloy is 15.7°C, and it has the property of easily melting by simply squeezing it in your hands or placing it in hot water.
One of the reasons is that it is not suitable for producing fine powder.
