In the transparent ceramics processing, the green body elaboration step is probably the most critical one. Among the known techniques, wet shaping processes are particularly interesting because they enable the particles to find an optimum position on

International audience; Transparent yttrium oxide (Y2O3) ceramics were processed by several densifications steps without any doping species. The green bodies were obtained by the aqueous way and sintered at high temperature under vacuum and then unde

Laboratory-scaled transparent samples have already been obtained, but upsizing the samples remains a technological challenge. Indeed, every step of the process can lead to defects that hinder optical properties. Among all of the processing steps, dry

In this paper we present our results on the sintering of α alumina ceramics by hot isostatic pressing. It describes a simple method for obtaining precise relative density values on our almost 100% dense samples. Then, transparency results are discus

Yb:CaGdAlO 4 is a promising laser media for femtosecond impulsions in the infrared, because of a broad emission line around 1 μm. This feature is related to the crystal structure where the doping ion, which substitutes Gd 3+ , is located in a disord
