| Research Abstract |
Garnet type ceramic scintillators have been produced by electromagnetic heating using far infrared rays. Fine powders of Y3Al5O12 (YAG) were pelletized, and they were used as starting samples. 28 GHz millimeter wave was irradiated to YAG and LuAG samples in air. The temperature at the surface of samples reached to 1600 oC for 30 min. The density of sintered YAG ceramics was 95 %, compared to the theoretical density of the YAG crystal. The observation of scanning electron microscope (SEM) images revealed that there is few pore in sinterd YAG ceramics. The results obtained indicate that the electromagnetic heating is effective for the densification of garnet type ceramics. The sintered YAG ceramics was translucent, but not transparent.
