摘要
A problem in the study of nanoparticles is that they will tend to grow at moderate temperatures. For example, most oxides (e.g. SnO2, ZrO2, MgO) will show significant grain growth at 400degreesC. This severely limits experimental studies that require measurements over an extensive temperature range. In this contribution we demonstrate that the incorporation of Al2O3 can significantly restrict grain growth in MgO and ZrO2 even at high temperatures.
