ZrO2Al2O3Y2O3相结构本文通过X衍射技术和多晶法计算研究了ZrO_2-Al_2O_3和ZrO_2-Al_O_3-Y_2O_3陶瓷材料的相结构变化。结果表明,在ZrO_2-Al_2O_3体系中,在低Al_2O_3含量时,主要相是单斜相。随着Al_2O_3含量增大,单斜相比率系数X_m下降,四方相含量明显增大。在ZrO_2-Al_2O_3体系中添加Y_...

求助。Al2O3-Y2O3-SiO2相图，最好能精确点。
在手边的胡德林编著的“三元合金相图”里只涉及到了Y2O3-ZrO2-Al2O3相图，没有Y2O3-SiO2-Al2O3相图...

【题目】 二氧化锆(ZrO2)是重要的耐高温材料,氧化钇(Y2O3)掺杂的二氧化锆(ZrO2)对O2有良好的传导性。 天然锆英石(ZrSiO4)含有FeO、 Al2O3、 C uO、 SiO2等杂质,工业以锆英石为原料制备ZrO2(掺杂Y2O3)的工艺流程如图:已知:①锆英石常温下与酸、 碱不反应,高温时能与烧碱反应生成可溶于水的N2 O3,Na2 ...
对Al2O3-ZrO2-Y2O3非晶陶瓷块体进行维氏硬度和单轴压缩测试,研究其常温力学性能,并与同组成完全析晶的陶瓷进行了对比.结果表明,Al2O3-ZrO2-Y2O3非晶陶瓷的维氏硬度为4.2GPa±0.1GPa,而多晶陶瓷的硬度为14.3GPa±0.2GPa;非晶陶瓷的硬度明显低于相同组成的多晶陶瓷.在单轴压缩中,非晶陶瓷和多晶陶瓷都发生了脆性...
