In this research, flux composed of 28 mol% BaO and 72 mol% CuO was employed as a novel sintering aid for BZY. Incorporation of nano-crystalline BaO-CuO flux, with a eutectic point of 890 degrees C, remarkably enhanced the sintering behavior of BZY due to the formation of a transient liquid phase, and a relative density of up to 97% of the theoretical density was obtained at 1300 degrees C with a short soaking time of 2 h.
