| Abstract | ||
| Lanthanum zirconates has been suggested as a thermal barrier coating for many high temperature applications. This study is focusing on the effect of different preparation parameters on the thermal conductivity of La2Zr2O7. We have used solid state reaction to form the zirconates powder was very good homogeneity. We have studied the effect of the intimal ZrO2/La2O3 ratio, and found the 50% to be the optimum. The effect of the sintering temperature has also been studied and 1100oc was chosen as the optimum sintering temperature. The sintering time was also studied, where 3 hours was proved to be enough to obtain a homogeneous single phase compound with affordable method. | ||
