Sintering Ability of Y-Doped BaZrO3 Refractory with Nano-CaCO3 and the Interaction with Ti2Ni Alloys
In this work, the effect of nano-CaCO3 additive on the sinter-ability of Y-doped BaZrO3 refractory and its interaction with Ti2Ni alloys was studied. The results showed that no second phase was observed in the Y-doped BaZrO3 refractory with nano-CaCO3 additive after sintering at 1750 ℃ for 6 h. The nano-CaZrO3 promoted the densification and the growth of grains of Y-doped BaZrO3 refractory. The relative density of Y-doped BaZrO3 refractory with nano-CaCO3 addition was about 97.5%. The melting experiment of Ti2Ni alloys was performed in the Y-doped BaZrO3 crucible with nano-CaCO3 additive at 1650 ℃ for 5 min, 10 min, and 15 min, respectively. Interaction analysis indicated that the thickness of the erosion layer was 2635 um, 3090 um, and 3689 um, respectively; and the content of oxygen was 0.412 wt%, 0.584 wt%, and 1.140 wt%, respectively.
