Abstract

The effect of Tb₂O₃ doping with different concentrations on the microstructures and mechanical properties of alumina arc tube was investigated under different sintering temperatures, and the influence of CaO doping alumina arc tube was also investigated for comparison. The results show that, contrasting to the coarse grain size and uniform microstructures of the alumina arc tube doped with CaO, heavy rare-earth Tb₂O₃ doping can decrease the grain size and enhance densification effectively. At relative lower sintering temperature, Tb₂O₃ doping can further eliminate the abnormal grain growth and improve the microstructure homogeneity and mechanical properties of transparent alumina arc tube.
