High Purity Tin Sn Powder CAS 7440-31-5,99%

Tin Sn Powder
Tin dust consists of a tetragonal or cubic silvery white metal. Tin's melting point equals 231.88. The Tin boiling point equals 2270. Tin density = 7.28. Tin metallic powder can be dissolved in concentrated hydrochloric and sulfuric acids, aqua regia (concentrated nitric), hot caustic liquid, cold dilute hydrochloric and dilute acidic solution, cold caustic fluid, acetic acid. In air, tin metal powder is relatively stable, but it is easily oxidized. This is especially true in humid air. Tin powder can be used in electronic industries and as a high-purity reagent.
Tin element occurs naturally in the earth crust. Tin powder consists of a white, silvery, soft metal. It is not soluble in water. Tin is used in the packaging of aerosols, food cans, and drinks. It can be combined with chemicals to make compounds. The inorganic compounds of tin are those that combine with other chemicals, such as chlorine or sulfur. Tin can be combined with carbon in order to produce organotins. (i.e. tributyltin or triphenyltin). These compounds can be used to manufacture plastics, food containers, plastic pipes and pesticides.

How are Tin Sn Powder manufactured?
Methods for preparing anti-oxidation powder, such as metal melts, sprays and other steps. Characteristics include: temperature control on the metal melting process, adding benzene, three azole nitrogen additives, and controlling the amount of liquid metal tin added (0.005%-0.008%). This method yields a -180 mesh metal powder which is used for friction materials.

: Tin-powder Uses
Tin powder can be used to make solder pastes and electric carbon products. It is also used for friction materials, structural metals, and oil-bearing materials.
This paste can be used to fill metal electrical gaps, as a lubricant or as a conductive paste.
Tin powder can be used as an additive to enhance the mechanical and electric properties of ceramics and metals.
Tin is the most commonly used non-ferrous material. It is used in many industries, including metallurgy and electronics. Tin powder will be increasingly used by electronics manufacturers as the lead-free trend continues to grow. In parallel, as environmental protection becomes more important, tin-powder's non-toxic environmental properties are increasingly used in medicine, chemical industries, light industry and food, health care products, art supplies, and packaging. Tin powder is becoming more and more important.

Conditions of storage for tin powder

Its dispersion and use will be affected by a damp reunion. Therefore, the product should be sealed and stored in cool, dry rooms, without exposure to air. Tin Nanoparticles must also be avoided during times of stress.
