Sintering behaviour and translucency of dense Eu2O3 ceramics

摘要: Abstract Eu2O3 ceramics have been obtained at sintering temperatures of between 1000 °C and 1550 °C. X-ray diffraction scanning electron microscopy, in combination with dilatometry experiments, allowed understanding the behaviour. Moderate grain growth followed an efficient densification process 1400 °C 1550 °C, which yielded high-density average size 4 μm. The had Young modulus 125 GPa, agreement previously published data. dense were translucent (35.1% transmittance 800 nm 0.8 mm thick discs), showing addition a slightly pink colour. We propose that high density 4 μm is responsible for this novel functionality.
