Tin
Tin
Physical Properties
Atomic number: 50
Atomic Weight: 118.71
Melting Point: 231.88°C
Boiling point: 2260°C
Density: 7.28g/cm
White glossy soft metal.
Chemical property
On the surface of tin generate two tin oxide protective film and remain stable in the air, but it accelerates the oxidation reaction when heating. Tin can react with the halogen and generate the four tin halides, besides it can also reset with sulfur.
Specification
Sn-5N(99.999%), <10 ppm
Sn-6N(99.9999%), <1 ppm
Sn-7N(99.99999%), <0.1 ppm
Application
Tin is used in the manufacture of compound semiconductor, high purity alloy, superconducting material, solder and as a dopant of compound semiconductor.
