Effect of La, Y Additions on ZrO2-mullite Nano-composite Ceramics by In-situ Controlled Crystallizing from Si-Al-Zr-O Amorphous Bulk

Abstract

Abstract:

Effects of Y₂O₃ and La₂O₃ doping on ZrO₂-mullite nano-composite ceramics, prepared by in-situ controlled crystallizing from the Si-Al-Zr-O amorphous bulk, were revealed by means of DSC, XRD, SEM and TEM technologies. The results indicate that the addition of Y₂O₃ and La₂O₃ (Y₂O₃ <1.8wt% and La₂O₃ <4wt%) can effectively reduce the melting temperatures of Si-Al-Zr-O based amorphous, limit the devitrification phenomenon and is beneficial for the formation of amorphous during cooling process, without changing the main crystalline phase precipitation. For Y₂O₃ single doping, Y is mainly dissolved in the zirconium oxide, stabilizes t-ZrO₂, and inhibits precipitation of the cordierite, and exerts little effect on the grain size. For both Y₂O₃ and La₂O₃ mixed doping, Y and La mainly locate in the glass phase, strengthen the grain boundary, of which La promotes the grain growth of ZrO₂ and mullite. The appropriate doping amount of Y₂O₃ and La₂O₃ should be in the range of 1.0wt%-2.0wt% and 0.6wt%-1.2wt%, respectively.

Key words: doping, amorphous, microstructure changes
