In order to examine easily synthetic conditions of uranyl molybdate, UO $_{2}$ MoO $_{4}$ , used for the reprocessing process study of spent nuclear oxide fuels in alkaline molybdate melts, the uranium molybdate compounds were produced from U $_{3}$ O $_{8}$ powder and anhydrous MoO $_{3}$ reagent. The results of having investigated them in solid state by using X-ray diffractometry and Raman spectrometry, it was confirmed that UO $_{2}$ MoO $_{4}$ could be synthesized by heating mixed powder of U $_{3}$ O $_{8}$ and MoO $_{3}$ with stoichiometric mole ratio at 770 $^{circ}$ C for 4 h under air atmosphere. Moreover, adding this UO $_{2}$ MoO $_{4}$ into Li $_{2}$ MoO $_{4}$ -Na $_{2}$ MoO $_{4}$ eutectic melt, most of the dissolved uranium species in the melt were observed as hexa-valent uranyl ions by absorption spectrophotometry.
