| titleOfInvention | Ytterbium-doped barium zirconate particles and mehtod for producing same |
| abstract | According to the present invention, there is provided a method for producing ytterbium-added barium zirconate particles represented by the composition formula (I) BaZr1-xYbxO3-[delta] (wherein x is a number satisfying 0.1 ≤ x ≤ 0.6, and [delta] represents the oxygen deficiency amount), the method contains: (a) a step of mixing a seed crystal of barium hydroxide, zirconium hydroxide, ytterbium hydroxide and ytterbium-added barium zirconate with water to obtain a first slurry; (b) a step of wet-milling the first slurry to obtain a second slurry containing particulate solid matter having an average particle size of 3.0 [mu]m or less; (c) a step of adding barium hydroxide to the second slurry to obtain a third slurry; (d) a step of hydrothermally reacting the third slurry to obtain a fourth slurry; and (e) a step of removing excess barium hydroxide by washing the fourth slurry with water after acid treatment; at that time, the Ba/(Zr+Yb) molar ratio of the slurries in the step (a) and the step (c) is set within a predetermined range. According to the present invention, it is possible to obtain ytterbium-added barium zirconate particles having a uniform composition, which does not include a heterogeneous phase, and which are fine and highly crystalline, by a liquid phase method suitable for industrial mass production at low cost. |
