Tin powder is green powder, the melting point of 231.88 ℃. The boiling point of 2270 ℃. Relative density 7.28. Soluble in concentrated hydrochloric acid, sulfuric acid, nitric acid and aqua regia, hot caustic solution, slowly dissolve in cold heat diluted hydrochloric acid and dilute nitric acid and dilute sulphuric acid, cold caustic solution, in acetic acid to dissolve more slowly. Stability in the air, but tin powder oxidation more easily, especially in the moist air to oxidation. Electronic industrial materials, used for high purity reagent.
Tin is at present our country one of the high degree of development and utilization of minerals in non-ferrous metal, widely used in metallurgy, electronics, electrical, chemical, building materials, machinery and food packaging industries. With the continuous development of utilizing trends on a global scale, electronics makers will be more tin powder material is applied to the 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. The importance of tin powder has been more and more obvious.
