At atmospheric pressure, tin exists in two forms: gray tin (α-tin) and white tin (β-tin). If white tin is placed in a cold environment with a temperature below 15 degrees Celsius, it will eventually start to \"crack\" and turn gray, forming what is known as the \"alpha\" form of tin.
The transformation of white tin into gray tin is also known as the \"tin plague,\" and this is the secret behind tin metal’s \"self-destruction.\" And if antimony or bismuth is present in tin, it can prevent the degradation of tin.
