The round tin bucket with handle in china tells you that in about 2000 BC, humans have started to use tin. The round tin bucket with handle in China tells you that the content of tin in the earth's crust is 0.004%, almost all in the form of cassiterite (tin oxide), in addition to a very small amount of tin sulfide ore.

The round tin bucket with handle in China tells you that tin has 14 isotopes, 10 of which are stable isotopes, namely: tin-112, 114, 115, 116, 117, 118, 119, 120, 122, 124. The metal tin is soft and easy to bend, with a melting point of 231.89°C and a boiling point of 2260°C. There are three allotropes.
round tin bucket with handle in china tells you that white tin is a tetragonal crystal system, unit cell parameters: a=0.5832nm, c=0.3181nm, the unit cell contains 4 Sn atoms, density 7.28g/cm3, hardness 2, ductility Good sex. Gray tin is a diamond-shaped cubic crystal system, the unit cell parameters are a=0.6489nm, the unit cell contains 8 Sn atoms, and the density is 5.75g/cm3. Brittle tin is an orthorhombic crystal system with a density of 6.54g/cm3.
Through the above introduction and analysis of a Round tin bucket with handle in china introduces the characteristics of tin, hope it helps you.
