Vanadium cesium uranium was yellow, fine-grained. It is phototropically indistinguishable from vanadium potassium uranium mine and is a biaxial crystal negative light. The refractive index of its anhydrous composite is N_p <1.83, N_m = 2.49, N_g = 2.70.2V = 45.5 °. No obvious fluorescence under UV irradiation. Monoclinic. Space group P2_1 / a. The unit cell parameters are: α_0 = 10.514, b_0 = 8.425, c_0 = 7.252 (A), β = 106.01 °, V = 617.5A ~ 3. Calculate the proportion of 5.4. The X-ray diffraction intensity spectra were 6.971 (100) (001), 3.605 (70) (021), 3.485 (60) (002), 3.344 (70) (211,202), 3.231 (50) (220). The chemical composition of the electron probe analysis of Cs_2O16.9-17.1%, K_2O 1.19-1.20, UO_3 49.5-49.8, V_2O_515.6-16.0. H_2O _ ((calculated)) 2.5%.
