3 Uses
3.1 Uses & Benefits
- It has an ability to absorb neutrons and hence it is used to make control rods in nuclear submarines. And this metal is also used in Plasma welding torches.
-
It alloys with iron, titanium and niobium are very useful.
- Tin-niobium alloy is used for producing superconducting magnets.
-
Tin salt known as a tin II chloride, it is used as a mordant and as a reducing agent for dyeing calico and silk.
