It is used in nuclear power, fiber optics and laser optics. It contributes to the activation of phosphorus in the smelting of ferrites and magnetic alloys of iron with nickel and cobalt. Er2 O3 oxide (sometimes borate) mixed with uranium oxide markedly improves power distribution as well as the technical and economic performance and safety of RBMK reactors. Erbium is present in the control rods of nuclear boilers. Like other metals of the lanthanide group, it is produced in the form of circles, wires, sheets
