の粒径は約０．３鴎程度である。[Detailed Description of the Invention] The tin powder is mixed and smelted and reduced to produce blister copper, which is purified by □ elution, poling, and electrolytic methods, and the particle size of the tin powder is about 0.3 mm. That's about it.
本発明の目的は、高純度で１＠微粒子の錫粉末を容易に
製造する方法を提供するにある。 。An object of the present invention is to provide a method for easily producing highly pure, 1@fine-particle tin powder. .

錫微粒子を製造することによって解決し得た。In the present invention, fine tin particles are produced by blowing molten gold and tin downward into an inert gas atmosphere from a nozzle using a preheated air stream and letting it fall underwater and rapidly cooling it. It was solved by doing.

筒８の先端ノズル４から一射させる。To explain based on the apparatus for implementing the method of the present invention, Figure 1 is a schematic diagram of the apparatus, 1 is an inert gas □ inlet,
8 is an inert gas injection cylinder, and inside it there is a heater 2.
And an external heater 3 is provided outside to preheat the inert gas to 250°C. The preheated inert gas is injected from the tip nozzle 4 of the injection cylinder 8.

ことが好ましい。If oxygen is mixed in the inert gas used in the present invention, it will react with tin at the tip of the nozzle to form an oxide, and the melt will crawl up the outer surface of the nozzle and fall as large drops, resulting in large particles. It is preferred that the purity of the inert gas is as high as possible, since the inert gases are miscible.

のであることが必要である。In addition, the melting point of tin is 232°C, and at a temperature just above this melting point, when it comes into contact with air, an oxide film forms on its surface in a relatively short time, making it easy to dissolve raw 1 and other 0 metals. Bill p,
Glass haze, melting of alumina, etc. must be suitable for reaction.
本発明の方法によると、簡単な装置で容易に粒径が３０

れる。According to the method of the present invention, the particle size can be easily reduced to 30 mm using a simple device.
By continuously producing fine particles of ~50 μm and using high-purity equipment and inert gas, high-purity fine particles can be obtained without mixing impurities.
