Abstract

We demonstrated the first successful fabrication of a transparent Lu ₃NbO₇ body by spark plasma sintering (SPS). First, Lu ₃NbO₇ powder was synthesized by a solid-state reaction of Lu₂O₃ and Nb₂O₅ powders at 1473 K for 7.2 ks and was sintered by SPS at 1723 K for 2.7 ks. The transparent Lu ₃NbO₇ body had a cubic defect-fluorite structure and uniform microstructure with an average grain size of 0.77 μm. The transmittance at 550 nm reached 68%.
