intermediate compounds containing both phosphorus and vanadium. The amount of phosphorus introduced was calculated using the expression x NH 4 VO 3 + (1 − x )(NH 4 ) 2 HPO 4 + Sb 2 O 3 , where x = 0.1–0.9 (batch B). The powders were ground in agate mortar
-performance superconducting films [ 9 , 10 ]. Knowledge of the processes that take place during decomposition of precursors as well as the formation of intermediate compounds is crucial to improve the performance of functional oxides. Moreover, in the synthesis of
(150–200 °C) and intermediate pH conditions. In contrast to the western part, where only Triassic hydrothermal process caused argillic alteration, in the eastern part both the Triassic and Paleogene hydrothermal processes developed clay mineral
instability of dinitro and higher polynitroaromatic compounds advise the use of a liquid-phase reaction [ 1 ]. The selective hydrogenation of nitro-compounds is commonly used to manufacture amines, which are important intermediates for dyes, urethanes
reactions, which were also observed by other authors [ 27 , 28 ]. It is suggested that the obtained FeSO 4 is transformed into an intermediate trivalent sulphate—Fe 2 O(SO 4 ) 2 or Fe 2 (SO 4 ) 3 . Masset et al. [ 27 ] proposed that Fe 2 (SO 4 ) 3 is

The mass losses of 40.88 and 42.86 % for (II) and (IV) in first step indicated by the feeble inflexion in TG curves corresponded to the formation of [VO(HL 1 )] and [VO(HL 2 )], respectively, as the probable unstable intermediates which undergo
