Praseodymium Boride, also called Praseodymium Hexaboride, is one of the rare earth borides, the molecular formula is PrB6. The rare-earth hexaborides have the cubic CaB6 structure , with rare-earth ions lying on a simple cubic lattice enclosing an octahedral B6 cage. 

Praseodymium hexaboride PrB6 and neodymium hexaboride NdB6 are also antiferromagnetic metals in which the magnetic properties are treated as being governed by localized magnetic moments of rare earth ions that interact with each other through conduction electrons (the Ruderman–Kittel–Kasuya–Yosida mechanism). 

Praseodymium hexaboride is believed to have a higher emission constant, and a lower volatility and congruent vaporization, which give rise to a lower operation temperature and longer service life comparing with conventional cathodic emission materials.
