Metal oxide modified multilayer oxide ceramic as well as preparation method and application thereof
The invention relates to a metal oxide modified multilayer oxide ceramic and a preparation method and application thereof, and the preparation method comprises the following steps: based on the total weight ratio of Y2O3, lanthanide oxides and other coloring element oxides in each layer of raw material oxide powder, selecting at least one layer of oxide powder, adding Al2O3, and uniformly mixing; the preparation method comprises the following steps: by taking the selected nth layer and the layer with the smallest Y2O3 weight ratio in the two adjacent layers as a comparison layer, quickly determining the addition amount of aluminum oxide in powder of each layer according to a formula m (Al2O3) = mmin (Al2O3) + a * delta m (Y2O3) + b * delta m (La)-c * delta m (O), a being 0.01-0.05, b being 0.02-0.1 and c being 0.01-0.04, adding according to a calculation result, and preparing the multilayer oxide ceramic which is not easy to deform after being pre-sintered, and has the characteristics of low cost and high efficiency. And the experiment exploration time and cost are greatly saved.
本发明涉及一种金属氧化物改性的多层氧化物陶瓷及其制备方法和应用，其基于各层原料氧化物粉体中Y2O3、镧系元素氧化物及其他着色元素氧化物的总重量比例，选取至少一层氧化物粉体添加Al2O3混匀，以选取的第n层与其所相邻两层中Y2O3重量比例最小的一层为对比层，按照公式m(Al2O3)＝mmin(Al2O3)+a*Δm(Y2O3)+b*Δm(La)‑c*Δm(O)，a的取值为0.01～0.05，b的取值为0.02～0.1，c的取值为0.01～0.04，能够快速确定各层粉体中氧化铝的添加量，按照计算结果进行添加，制备的多层氧化物陶瓷预烧结后不易变形，大大节省实验摸索时间和成本。
