Journal ArticleDOI
Effect of Europium Concentration on Densification of Transparent Eu:Y2O3 Scintillator Ceramics Using Hot Pressing
TL;DR: In this article, Europium (Eu) was found to act as a solid-state sintering aid in Y2O3 optical ceramics by controlling ionic diffusivity, which in turn leads to enhanced optical transparency.
Journal ArticleDOI
Sintering Behavior and Optical Properties of Yttria
TL;DR: In this paper, the relative density/grain size trajectory has been drawn and hypotheses concerning the mechanisms controlling grain growth and densification were formulated, and the optical properties were measured in the UV, visible, and infrared ranges.

A. Ratsimba,A. Zerrouki,Nicolas Tessier-Doyen,Benoît Nait-Ali,Damien André,P. Duport,A. Neveu,Naveen Mani Tripathi,F. Francqui,Gaëlle Delaizir +9 more
TL;DR: In this paper, the effects of the initial yttria particle characteristics on the powder bed behavior and the process conditions (laser power, scanning speed, hatching space) on the sintering/melting of 3D printed objects were investigated.

TL;DR: In this paper, a two-step sintering method was proposed to enhance the mechanical properties of Y2O3 by adjusting the concentration of each dopant cation (Si4+, Er3+, Yb3+, Al3+, and Ti4+) in order to obtain a higher dopant:yttria molar ratio.
