Uses
Uses & Benefits
- 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.
- Holmium metal has an ability to absorb neutrons, so this metal is used in nuclear reactors to keep the chain reactions of elements under control.
- Alloys of Holmium are used to produce Magnet.
