Applications

Production of infrared lasers as well as magnetic alloys. Praseodymium monotelluride is used to adjust properties of resistance, electromotive force, strength of thermoelectric alloys based on rare earth elements. Alloy of praseodymium with germanium and silicon is a superconducting material. Application of praseodymium in electric vacuum equipment allows to increase efficiency of cathodes and also magnetic cores, this metal is in demand for steel alloying, control of nuclear magnetic resonance.
