FLUORESCENT ZIRCONIA MATERIAL
형광성 성분을 함유하며, 소정 파장의 광에 의해 여기되어 형광을 발하는 형광성 지르코니아 재료로서, 상기 형광성 성분은, YSiO:Ce, YSiO:Tb, (Y,Gd,Eu) BO, YO:Eu, YAG:Ce, ZnGaO:Zn, BaMgAlO:Eu 중 적어도 1 종을 포함하는 형광성 재료를 포함하고, 또한 상기 형광성 재료는, 산화 분위기하 1300 ∼ 1600 (℃) 의 범위 내의 온도에서 소성 처리 후에 형광을 발할 수 있는, 상기 형광성 지르코니아 재료가 제공된다.
Provided is a fluorescent zirconia material. When a frame (14) is fired at a high temperature of 1300-1600°C, a fluorescent property, i.e., an ability to generate fluorescence upon UV irradiation, is imparted to the frame (14) comprising zirconia, due to Eu 2 O 3 which is contained in the zirconia material constituting the frame (14). For example, when the cross section surface of the frame (14) is irradiated with a UV lamp, a black light or the like upon breakage, the frame generates fluorescence and thus shows traceability. When irradiated with a blank light, the frame (14) generates blue fluorescence and a thin part in an upper layer (18) and a part not provided therewith also have the same fluorescent property as the upper layer (18), which brings about an esthetical merit too.
