High-strength ceramic from zirconium dioxide with an additive of the oxides of yttrium and iron

Effect of iron impurity on structural development in ball-milled ZrO2–3mol% Y2O3

“…Stefanic et al [19] observed that the presence of impurities in the ball-milled m-ZrO 2 powder significantly influenced the stability of the t-ZrO 2 product. It was found that addition of iron oxide facilitates the activation of diffusion processes at grain boundaries, and significantly reduces the sintering temperature in the materials of the system [20]. Verkerk et al [21] studied the effect of impurities on sintering and conductivity of yttria-stabilized zirconia.…”
