CAS Number 7440-31-5 Tin Metal Powder 3-5μm formula Sn for High purity reagent

Green powder, the melting temperature of 231.88 ℃.The boiling point of 2270 ℃.The relative density is 7.28.Soluble in concentrated hydrochloric acid, sulfuric acid, wang shui, concentrated nitric acid, hot caustic soda solution, slowly dissolve 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 the air, but the tin powder is easy to oxidize, especially in humid air.Electronic industrial materials used for high purity reagents.

Widely used in metallurgy, electronics, electrical, chemical, building materials, machinery and food packaging industries.As the lead-free trend continues to grow worldwide, electronics manufacturers will be more likely to apply tin powder to their products.At the same time, along with the unceasing enhancement of environmental consciousness, tin powder, non-toxic environmental protection properties will make it in the future be continuously applied to medicine, chemical industry, light industry, food, health care, art supplies, and other areas of the packaging.
