Overview of Tin (Sn) Powder

Tin powder is a silvery-white, shiny, soft metal (tetragonal and cubic), ductile. The melting temperature of 231.88 ℃.The boiling point of 2270 ℃.The relative density is 7.28. Tin powder is soluble in concentrated hydrochloric acid, sulfuric acid, aqua regia, concentrated nitric acid, hot caustic solution, slowly soluble in cold dilute hydrochloric acid, dilute nitric acid and hot dilute sulfuric acid, cold caustic solution, in acetic acid more slowly. Stable in air, but in powder is more easily oxidized, especially in humid air more easily oxidized. Tin powder is a material used in the electronic industry and used as a high purity reagent.
Tin is a natural element in the earth’s crust. It is a soft, white, silvery metal that does not dissolve in water. It is found in brass, bronze, tin and some welding materials. Tin is used to pack cans of food, drinks and aerosols. Tin can combine with other chemicals to form compounds. Combinations with chemicals such as chlorine, sulfur, or oxygen are called inorganic tin compounds (i.e., stannous chloride, stannous sulfide, and stannous oxide). They are used in toothpaste, perfumes, soaps, food additives and dyes. Tin caGrayish green powder, melting point 231.88℃. The boiling point is 2270℃. The relative density is 7.28. Soluble in concentrated hydrochloric acid, sulfuric acid, aqua regia, concentrated nitric acid, hot caustic soda solution, slowly soluble in cold dilute hydrochloric acid, dilute nitric acid and hot dilute sulfuric acid, cold caustic soda solution, dissolved more slowly in acetic acid. It is stable in air, but in powder is easier to oxidize, especially in humid air. Materials for the electronics industry, used as high-purity reagents.n also combine with carbon to form organotin compounds (i.e., dibutyltin, tributyltin, triphenyltin). These compounds are used in the manufacture of plastics, food packaging, plastic pipes, pesticides, paints and insecticides. Tin, as well as inorganic and organotin compounds, can be found in the air, water, and soil, naturally occurring in rocks or near places of mining, manufacture or use.

 How is Tin (Sn) Powder Produced?

Anti-oxidation tin powder preparation methods, including metal melt, spray and other steps, whose character is: the temperature of the molten tin liquid metal melting process control in 295 ~ 310 ℃, it is joined benzene and three azole nitrogen additive in the process of atomization, the addition amount of melted metal tin liquid 0.005% ~ 0.008%, and the weight of the atomization process of ventilation with the high-pressure airflow control in 7 ~ 8.2 m3 / min. The -180 mesh metal tin powder obtained by this method is used in the field of friction materials.

Applications of Tin Sn Powder:

Tin powder is mainly used in the manufacture of solder paste, electric carbon products, friction materials, oil-bearing and powder metallurgy structural materials.It can also be used as metal electrical filler, lubricant and conductive paste.Tin powder can also be used as a wild phase to effectively improve the mechanical and electrical properties of metals and ceramics.Tin is one of the most widely used non-ferrous metals, widely used in metallurgy, electronics, electrical appliances, chemical industry, building materials, machinery and food packaging industries. As lead-free trends continue to develop worldwide, electronics manufacturers will increasingly incorporate tin powder into their products. At the same time, with the increasing awareness of environmental protection, tin powder non-toxic environmental properties will make it in the future will be constantly applied to medicine, chemical industry, light industry, food, health care, art supplies and other packaging fields. The importance of tin powder has become increasingly apparent.

5 FAQs of Tin powder

Q1

Is tin powder stable?

Tin powder is soluble in concentrated hydrochloric acid, sulphuric acid, aqua regia, concentrated nitric acid, and hot caustic solution. It is also slowly soluble in cold dilute hydrochloric acid, dilute nitric acid, hot dilute sulphuric acid, cold caustic solution, and more slowly dissolved in acetic acid. The tin powder is stable in air, but it is easier to oxidize, especially in the humid air.

Q2

Tin dust can cause fire and explosion？

Tin dust is flammable and explosive, and if the conditions are met, it can cause fire and explosion. To monitor the concentration, dust meters need to be installed at the place of use.

Q3

What are the morphologies of tin dust?

Common powder shapes include spherical, cubic, flaky, etc., and the particle size can be adjusted according to the need. Generally speaking, smaller particle-size tin powder has better fluidity, making it easier to achieve uniform coating and fine spraying.

Q4

What are the application areas of tin powder?

It is used in various applications, markets and technologies, such as diamond tools, powder metallurgy, electronics and radiation shielding. Typical applications may include pressed and sintered components, bearings and bushings, metallurgical alloying, chemical processes, friction components, surface engineering, decoration, soldering and brazing.

Q5

What is the method of making tin powder?

The centrifugal atomisation method of making conventional tin powder is widely used in industry. The main mechanism is to fill a large airtight container with an inert gas. A high-speed rotating disc is fixed at the top of a high-speed motor, and the disc speed is adjustable; the molten liquid alloy with qualified composition check is flowed (dripped) to the rotating disc through a pipe, and the centrifugal force generated by the rotation of the disc throws out the liquid solder, which, driven by the surface tension of the metal droplets, balloons into small droplets, which cool down under the inert gas environment to form spherical metal particles, which are gathered at the bottom of the closed container, and tin powder is finally obtained.
