What is tin pest, also known as tin disease?

Short Answer

Expert verified

Tin pest refers to a phenomenon where the element tin undergoes transformation and degrades the quality of tin objects at lower temperatures.

Step by step solution

01

Tin

Tin is one of the chemical elements that appear as a silvery metal. Its chemical symbol is Sn obtained from its Latin name,stannum.

Information about tin

02

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.
