Q. What are the uses of Tellurium?
Tellurium is used primarily as an additive to steel to increase its ductility. It is also used as an additive to some catalysts, used in cracking of petroleum, as a colouring material for glasses and as an additive to lead to increase its strength and make it corrosion resistant. Polonium - 210 is used mainly for the production of neutron sources; for these, polonium is alloyed with elements such as beryllium.
