The reactions between rubidium carbonate and vanadium pentoxide were performed at different high temperatures. Four reaction products of the compositions: I. Rb 2 O · V 2 O 5 ; II. 2 Rb 2 O · V 2 O 5 ; III. 3 Rb 2 O · V 2 O 5 ; and IV. Rb 2 O · 4 V 2 O 5 were obtained. According to the determination of Rb and the X‐ray powder photographs of the products the existence of rubidium metavanadate (RbVO 3 ) and rubidium pyrovanadate (Rb 4 V 2 O 7 ) was confirmed. On the other hand, the preparation of a pure rubidium orthovanadate (Rb 3 VO 4 ) and rubidium tetravanadate (Rb 2 O · 4 V 2 O 5 ) was not successful. The diffraction pattern of Rb 2 O · V 2 O 5 obeys hexagonal indexing with lattice dimensions a = 7.347 and c = 13.608 Å.
