The high purity tin generally refers to the purity of more than 99.999 percent tin, it is widely used in semiconductors, superconducting materials, and engineering physics department. Production of high purity tin general with a common refined tin raw material, the method of production of electrolytic purification method, the electrolysis of a vacuum volatile purification and electrolysis zone melting purification method of three.
CAS No.:7440-31-5
Molecular Formula: Sn
Melting point: 231.89 ℃
Boiling point: 2507 ℃
Production of high purity tin began in 5O years of the 2O century. The Soviet Union in the early 6O's power of dissolving a chemical purification of an electrolytic regional melting method to produce high-purity tin, 197O improved vacuum volatile electrolysis region melting. In 1969, China began producing high-purity tin, the first electric solution, and later changed to the purification method of electrolysis a vacuum volatile. Zone melting recrystallization method to produce high-purity tin.
