2Step 2: Tin pest

Tin has two allotropes. White tin is stable above\({\bf{13}}{\bf{.}}{{\bf{2}}^{\bf{^\circ }}}{\bf{C}}\), and is malleable like other metals. Grey tin isa more stable allotrope below \({\bf{13}}{\bf{.}}{{\bf{2}}^{\bf{^\circ }}}{\bf{C}}\)and is brittle.

 

As temperature decreases and white tin changes to grey, it starts at one spot, and the transformation proceeds to spread like a disease. The name "tin disease" comes from this process.
