Abstract

本发明公开了一种氧化铈/氧化钇复合氧化锆纳米粉体及其生产方法,所述纳米粉体组分和摩尔百分比含量包括氧化铈8-10%,氧化钇复合氧化锆90~92%,氧化钇复合氧化锆中,氧化钇的摩尔百分比含量为3%-8%。本发明制备方法简单,成本低,易实现产业化生产。氧化铈/氧化钇复合氧化锆纳米粉粒度分布在30-70nm纳米,形状为球形或近球形结构,内部各组份之间结合紧密,流动性好,具有良好的输送特性,可直接应用于结构陶瓷件的成型,且成型的结构件具有高的强韧性和耐高温性能、优良的抗热冲击性能、耐磨性,具有良好的市场应用前景及商业价值。
The invention discloses cerium oxide/yttrium oxide composite zirconia nano powder and a production method thereof. The compositions in molar percentage of the nano powder comprise 8 to 10 percent of cerium oxide and 90 to 92 percent of yttrium oxide composite zirconia which contains 3 to 8 percent of yttrium oxide in molar percentage. The preparation method has low cost and is simple and easy to realize industrialized production. The particle size distribution of the cerium oxide/yttrium oxide composite zirconia nano powder is between 30 and 70nm, and the shape of the powder is in the shape of a sphericity or a nearly spherical structure; moreover, the inner compositions of the powder are closely combined and have ideal fluidity, good conveying characteristic so as to be directly used in the forming of a structural ceramic piece; moreover, the formed structural piece has high obdurability and high temperature-resisting performance, excellent thermal shock resistance and abrasion resistance, thereby having enormous market application prospect and commercial value.
