Lutetium silicide（LuSi2） 

Common name: lutetium silicate
English name: Lutetium silicide
Chemical formula: LuSi2

Application: Used in semiconductor, electronics, materials and other fields, such as semiconductor lasers, 

metal lutetium fibers, etc. In addition, lutetium can also be used as fuel for nuclear reactors, 

and its radioactive decay product lutetium-176 has a very long half-life, 

which can stably control the energy output of nuclear reactors in the long term.
