CERAMIC COMPOSITION AND PRODUCING METHOD OF CERAMIC COMPOSITION
To provide an inexpensive material having a light-emitting function.SOLUTION: A ceramic composition consists of two phases of a corundum phase and a CeAl11O18 phase, and contains the CeAl11O18 phase in an amount of 0.5 mol% or more and 5 mol% or less. A producing method of the ceramic composition comprises the steps of: mixing cerium oxide powder and aluminum oxide powder; obtaining a compact by forming the material obtained by the mixing; and firing the obtained compact at a temperature of 1,400°C or more and 1,700°C or less in a reducing atmosphere.SELECTED DRAWING: Figure 1
【課題】発光機能を有する安価な材料を提供すること。【解決手段】セラミック組成物は、コランダム相とＣｅＡｌ11Ｏ18相との二相からなり、前記ＣｅＡｌ11Ｏ18相を０．５モルパーセント以上５モルパーセント以下含む。このセラミック組成物の製造方法は、酸化セリウム粉末と酸化アルミニウム粉末とを混合し、混合して得られた材料を成形して成形体を取得し、取得した成形体を還元雰囲気において１４００度以上１７００度以下の温度で焼成する工程を有する。【選択図】図１
