Tin Sn Powder CAS 7440-31-5

About Tin Sn Powder:
The appearance of tin powder is off-white, with a metallic luster, and its particle size varies from micron to millimeter. The density of tin powder is relatively low, only 7.3g/cm³ so that it can be suspended in the air and blown apart by the wind. In addition, the melting point of tin powder is 232℃, and the boiling point is 2260℃; its hardness and ductility are moderate, and it has good processing properties. 
Regarding chemical properties, Tin powder has good corrosion resistance and is easily oxidized or damaged by corrosion. It reacts slowly with chemicals such as strong acids, bases, and oxidants, so in some specific environments, such as chemical, food, and pharmaceutical industries, the tin powder can be used as a sealing material or packaging material. In addition, tin powder has good electrical conductivity and can be used to manufacture electronic products such as circuit boards, electronic components, and solar cells.

Specification of tin powder:

Application of Tin Powder :

Tin powder is a significant metal powder material with excellent chemical and physical properties, widely used in various fields. Among them, the application of tin powder in the electronics industry is the most important. 

In electronics, tin powder can manufacture electronic products such as circuit boards, components, and solar cells. In the circuit board manufacturing process, tin powder can be used as a solder coating on the pad and can also be used as a solder on the wire on the board to connect the pad. In addition, tin powder can also be used to manufacture electronic components, such as capacitors, resistors, and diodes. In solar cell manufacturing, tin powder can be used as an electrode material to convert solar energy into electricity. 

In addition to its applications in the electronics industry, tin powder can also be used in machinery manufacturing. In machinery manufacturing, tin powder can make metal alloys, solder, and sealing materials. Tin alloy has the advantages of high strength, corrosion resistance, and good processing properties and is widely used in mechanical manufacturing. Tin powder can be used as a solder, joining different metals to form a strong welding joint. In addition, tin powder can also be used as a sealing material, effectively preventing the leakage of gases, liquids, and other substances. 

In the food packaging industry, tin powder can manufacture food packaging containers and sealing materials. Tin alloy has corrosion resistance, non-toxicity, and aesthetic characteristics and is widely used in food packaging. In addition, tin powder can also be used in chemical, pharmaceutical, and textile industries.

 Production Method of Tin Powder :

The main production methods of tin powder include melt injection, gas atomization, and rotary casting. These methods are designed to melt tin ingots and then spray, atomize, or spin the molten tin into tin beads or powder through a specific process technology. 

Melt injection is a commonly used powder production method; its main process includes melting, extrusion, injection, and condensation steps. First, the tin ingots are melted in the melting furnace, then the molten tin is extruded into fine tin beads by an extruder, and then the tin beads are evenly sprayed into the air by a special nozzle to cool them into tin powder. The advantage of this method is that it can produce fine particle size and uniform distribution of tin powder. Still, it will produce a lot of waste gas and heat in the production process, causing certain environmental pollution. 

Gas atomization is an advanced method for producing tin powder. Its main processes include melting, atomization, cooling, and crushing. First, the tin ingots are melted in the melting furnace, then the molten tin is sprayed onto the cooling wall through high-pressure gas to form tin beads, and then the tin beads are cooled into tin powder. The advantages of this method are that it can produce fine particle size and uniform distribution of tin powder, and the production process is more environmentally friendly, but the production cost is higher. 

Rotary casting is a more traditional tin powder production method; its main process includes melting, casting, cooling, and crushing steps. First, the tin ingots are melted in the melting furnace, then the molten tin is cast into tin strips by a rotating casting machine, and then the tin strips are cooled and broken into tin powder of a certain size. The advantage of this method is that the production process is relatively simple and the cost is low, but the produced tin powder has a large particle size and needs to be further broken. 

In addition to the above methods, there are electrolysis methods, chemical deposition methods, and other methods for preparing tin powder. The electrolytic method is mainly through electrolytic reduction technology to reduce tin ions to tin powder, which is suitable for preparing high-purity tin powder. The chemical deposition method is mainly through a chemical reaction to reduce tin ions into tin powder, and this method can also prepare high-purity tin powder.
