| 摘要: 研究了共沉淀法制备Yb/Ho∶Y2O3纳米粉末及其透明陶瓷的烧结工艺，采用Y(NO3)3、Yb(NO3)3和Ho(NO3)3的混合溶液为母盐溶液，以氨水为沉淀剂，在不同pH值下，用共沉淀法制备得到了碱式硝酸盐前驱体沉淀。1 100 ℃煅烧2 h得到Yb/Ho∶Y2O3纳米粉末。采用0.5wt%的TEOS(正硅酸四乙酯)为添加剂，1 700~1 850 ℃真空烧结15~25 h后，得到了Yb/Ho∶Y2O3透明陶瓷。 | |

| Abstract: A mixed solution of yttrium nitrate, ytterbium nitrate and holmium nitrate solution were used as a mother solution, and aqueous ammonia was used as a precipitant to synthesize Yb/Ho∶Y2O3 nanopowders by co-precipitation. Nitrate precursors were obtained via a co-precipitation method under different pH values. Yb/Ho∶Y2O3 nanopowders were synthesized by sintering at 1 100 ℃ for 2 h. With the addition 0.5wt%TEOS as a sintering aid, transparent Yb/Ho∶Y2O3 ceramics were fabricated by vacuum sintering at 1 700~1 850 ℃ for 15~25 h. | |
