The X-ray single crystal structure determination of Lu₂O₃ sesquioxide and of polycrystalline transparent ceramic fabricated by the unconventional spark plasma sintering (SPS) method is presented for the first time. High quality single crystals of Lu₂O₃ samples were obtained by using both the micropulling-down (渭-PD) method and the laser heated pedestal growth (LHPG) technique. The SPS method is promising for obtaining high-density ceramics with fine grains at a relatively low temperature within a short holding time. The structural characterizations helped to complete information about the cubic structure of Lu₂O₃ sesquioxide, not clear until now in the literature from only polycrystalline samples and has raised doubts among many researchers.
