Thermodynamic characteristics of Li2MoO4, Li2W0.85Mo0.15O4 single crystals and stability direction for alkali molybdates

Thermodynamic properties of single crystals based on lithium tungstate by reaction and DSC calorimetry

“…The standard formation enthalpies for Li2W1-0.0125Mo0.0125O4 and Li2WO4 single crystals were determined using an automated solution calorimeter. The detailed design of the calorimeter and experimental procedure were described in papers [3,7]. To determine the standard formation enthalpies, a thermochemical cycle was designed in such a way that dissolution enthalpies of lithium carbonate, molybdenum oxide, and potassium tungstate were compared with dissolution enthalpies of single crystals.…”

“…Molybdates and tungstates of the first and second groups are promising materials for high-energy physics and new energetics [1][2][3][4][5]. In particular, to search for rare events, such as double neutrinoless beta decay, elastic coherent neutrino scattering, single crystals in lithium molybdate -lithium tungstate system with isotopes 100 Mo, 186 W are widely used.…”

Calorimetric Determination of the Formation Enthalpies of Cs Polymolybdates at 298.15 K and 0.1 MPa

“…The analysis of the bibliography shows that the thermodynamic properties of certain alkali molybdates: Li 2 MoO 4 , − Na 2 MoO 4 − and Na 2 Mo 2 O 7 , K 2 Mo n O 2 n +1 with n = 1, 2, 3, 4, and 8, Rb 2 MoO 4 , Cs 2 MoO 4 ,− and Cs 2 Mo 2 O 7 , , Cs 3 Na­(MoO 4 ) 2 , and alkaline earth molybdates: MgMoO 4 , CaMoO 4 , , , SrMoO 4 , and BaMoO 4 , have been experimentally determined by various methods. A critical analysis of these results has been recently published as part of the Organization for Economic Co-operation and Development-Nuclear Energy Agency’s (OECD-NEA) chemical thermodynamics project …”
