The enthaply of formation of potassium chromate(V), K₃CrO₄(c)

Abstract

Calorimetric measurements on potassium chromate(V), K3CrO4(c), and related substances have provided enthalpies that lead to ΔHf0 = −370 ± 2 kcal mol−1 for K3CrO4(c) at 298 K.

Static and dynamic magnetic properties of K3CrO4

“…Structural analysis of the K3CrO4 sample using powder XRD shows a single-phase product for which the peak positions are consistent with the previously reported cubic space group P213 [9]. The refined lattice parameter is a = 8.3158 (10) Å and the unit cell volume is V = 575.05(22) Å 3 (the fitted XRD data are shown in Fig. S2, the atomic coordinates are listed in Table S1).…”

“…In the literature, different synthesis routes have been described [9,10], including a recent investigation in which in situ high-temperature X-ray diffraction measurements were performed during the reduction of the Cr 6+ compound K2CrO4, which led to the formation of different KxCrOy compounds including K3CrO4 [11].…”

In situ high-temperature X-ray diffraction studies of reduction of K2CrO4 and the formation of KxCrOy compounds

“…It is well known that potassium and Cr are known to form a number of crystallographically well-defined K x CrO y compounds, such as K 3 CrO 4 (Johnson, 1978), K 3 CrO 8 (Cage et al , 1999), KCr 3 O 8 (Vidya et al , 2006), and KCrO 2 (Zafar Ali et al , 2013). The reduction products of K 2 CrO 4 may contain many Cr 5+ , Cr 4+ , and Cr 3+ compounds.…”
