Tin Powder Properties

Features of Tin Sn powder CAS 7440-31-5 :
Grayish green powder, melting point 231.88℃. 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, dissolve more slowly in acetic acid. It is stable in air, but tin powder is easier to oxidize, especially in humid air. Materials for the electronics industry, used as high-purity reagents.

Specification of tin powder:





Bulk Density



Tin(Sn) Nanoparticle








Application of tin powder:

1. Metal electric padding, lubricant, conductive slurry…….

2. Used as wild phase, can enhance mechanical and electric conduction property of metal and ceramic effectively.

Storage Conditions of tin powder:

Damp reunion will affect its dispersion performance and using effects, therefore, this product should be sealed in vacuum and stored in cool and dry room and it should not be exposure to air. In addition, Tin Nanoparticles should be avoided under stress.
