Tin Metal
MATERIAL OVERVIEW
Characteristics: Silver-white, ductile solid (beta-form). Changes to brittle grey (alpha) tin at temperatures below 18°C but the transition is normally very slow. Soluble in acids, and hot potassium hydroxide solution. Insoluble in water. Elemental tin has low toxicity, but most of it's compounds are toxic.
Hazards: All organic tin compounds are toxic. Tolerance, 2 mg/m3 of air; (organic compounds, as Sn), 0.1 mg/m3 of air.
Application: Tin could be used in different fields, according to its purity. Mainly applied for basic material such as making compound semi-conductor, high purity alloy, ultra low temperure cooling alloy, ultra conductor material,solder and dopant of compound semi-conductor, ITO.etc.
