Approximating the Liquidus Surface of the ZrO2 ― Y2O3 ― La2O3 Phase Equilibrium Diagram with Reduced Polynomials A mathematical model of the liquidus surface of the ZrO 2 ― Y 2 O 3 ― La 2 O 3 phase equilibrium diagram was constructed by the use of reduced polynom... ER Andrievskay...
研究过程中,采用热等静压获得了全致密的 MgO–Y2O3–ZrO2 纳米复相陶瓷,改变加入 ZrO2 的 浓度,研究了 ZrO2 浓度对氧化钇晶格常数,复相陶 瓷硬度以及红外透过率的影响,结果表明: MgO–Y2O3–ZrO2 纳米复相陶瓷由于其增强的机械 性能,有望成为红外透明材料. Harris 等[47]在 2014 年利用火焰喷雾热解法制备 出...

In addition, this is markedly superior to the results modified by Al2O3 [14–16], SiO2 [17], La2O3 [18], TiO2 [19, 20], ZrO2 [21, 22], CeO2 [23, 25], MgO [26], and LiAlO2 [27]. Therefore, it is proposed that 1.0 wt% Y2O3 coating is an outstandingly effective way ...
Stoichiometric oxides and carbonate of PbO, SrCO3, La2O3, ZrO2, SnO2, and TiO2 were weighed and well mixed according to the formula, in which an additional 5 mol% PbO was added to stabilize the antiferroelectric structure [13]. The mixture was calcined at 900 ◦C for 3 h and rather ...
According to the XRD patterns, the ZrO2–Y2O3–Al2O3–CoO–CeO2–Fe2O3 ceramics under study are characterized by clear peaks in the m-ZrO2 and t-ZrO2 phases (Figure 1). We found a gradual increase in the peak heights of the t-ZrO2 phase for the materials with an increase in the ...
