Ytterbium Boride Powder, also called Ytterbium Hexaboride, is one of the rare earth borides, the molecular formula is YbB6. Ytterbium hexaboride is black crystalline powder. Among all REB6, YbB6 is especially attractive for its relatively low density, high mechanical strength, and high melting point characteristics. The crystalline form of YbB6 has cubic Pm-3m space group symmetry like most of the rare-earth hexaborides (REB6), resembling the crystal structure of CsCl. Rare-earth ion and octahedral B6 occupy Cs site and Cl site respectively, and the octahedral B6 cluster links to each other by strong covalent bonds providing high hardness characteristics.YbB6 is traditionally synthesized through mechano-chemical processes, high temperature sintering methods, vacuum calcination, and combustion synthesis.
