The tin powder is a gray-green powder having a melting point of 231.88 ° C and a
boiling point of 2270 ° C. The relative density of tin powder is 7.28. It is soluble in concentrated hydrochloric acid, sulfuric acid, aqua regia, concentrated nitric acid, hot caustic solution, slowly dissolved in cold dilute hydrochloric acid, dilute nitric acid and hot dilute sulfuric acid, cold caustic solution, slowly dissolved in acetic acid. Tin powder is stable in the air, but tin powder is more susceptible to oxidation, especially in humid air. A material used as a high purity reagent in the electronics industry.
Tin is one of the minerals with high development and utilization of non-ferrous metals. It is widely used in metallurgy, electronics, electrical appliances, chemicals, building materials, machinery and food packaging. As lead-free trends continue to grow globally, electronics manufacturers will increasingly apply tin powder materials to their products. At the same time, with the increasing awareness of environmental protection, the non-toxic and environmentally friendly properties of tin powder will continue to be applied to the packaging fields of medicine, chemicals, light industry, food, health care and art supplies in the future. The importance of tin powder has become more and more obvious.
