Physicochemical property data, such as density, electrical conductivity, and pH of aqueous solutions LiB(OH)4, Li2B4O5(OH)4, LiB5O6(OH)4 have been accurately determined at different temperatures. Density values were given from 288.15 K to 323.15 K, conductivity 293.15 K. The properties represented by semiempirical equations functions concentration. mole fractions polyborates obtained in lithium borate solutions, their distribution relevant mechanism also suggested.
The phase transition performance of the CaCl2 · 6H2O–Ca(NO3)2 4H2O composite salt system with nucleating and thickening agents was investigated in this paper. prepared by adding Ca(NO3)2 (12 wt%) to 6H2O. Different including SrCl2 6H2O, SrCO3, BaCl2, BaCO3, Na2B4O7 10H2O, H3BO3 NH4Cl were used address problems segregation supercooling phenomena during change process. results show that single agent 6H2O or mixture 2 wt% 1 BaCl2 0.5 carboxyl methyl cellulose is most suitable for system. latent...
A systematic study on the structure, stability, and Raman spectra of metaborate anion hydrated clusters, B(OH)4(-)(H2O)n, (n = 1-15) was carried out by DFT in both gaseous aqueous phase at B3LYP/aug-cc-pVDZ level; all these stable configurations were described, most clusters chosen. The hydrogen bonds those described three different items: symmetrical double bonding (DHB), single (SHB), interwater (WHB). distance SHB is shorter than that DHB, multiple SHBs are more a DHB. In small size ≤ 5),...
The solubility and behavior of phase transformation for MgB4O7 + H2O were studied at 298.15 K by the method isothermal dissolution equilibrium. results indicated that equilibrium solid MgB4O7·9H2O was kept in aqueous solution 240 h started to transform into inderite (MgB3O3(OH)5·5H2O) after h. concentration liquid with respect is 0.03494 mol·kg–1 as metastable solubility. isopiestic solubility, osmotic coefficient, water activity saturated ± 0.01 determined first, obtained values 0.03536...
Ion association and hydration clusters in aqueous lithium borate solution are extremely important to understand some extraordinary properties of borates. In the present work, polyborate distribution LiBO2 was investigated through Raman thermodynamics equilibrium analysis. Geometry stability hydrated LiB(OH)4(H2O)n up n = 8 were calculated at B3LYP/aug-cc-pVDZ level. Three different types ion association, namely, contact pairs (CIP), solvent-shared (SIP) solvent separated (SSIP) obtained;...
Lithium, as a green energy metal used to promote world development, is an important raw material for lithium-ion, lithium–air, and lithium–sulfur batteries. It challenging directly extract lithium resources from brine with high Mg/Li mass ratio. The microstructure study of salt solutions provides theoretical basis the separation magnesium. changes in hydrogen bond network structure ion association Li2SO4 aqueous solution Li2SO4-MgSO4-H2O mixed were studied by Raman spectroscopy. SO42− fully...
The stable solid–liquid phase equilibrium in the ternary system MgSO4 + MgCl2 H2O at 263.15 K was investigated with isothermal dissolution method, and diagram plotted. Two invariant points cosaturated MgSO4·7H2O ice MgCl2·6H2O MgSO4·7H2O, three crystallization fields corresponding to (Bis), (Eps), ice, univariant curves were determined system. Compared 273.15 K, region ice–salt point are found K. Neither solid solution nor double salts
The solubility isotherms of the two ternary systems (MgCl2 + MgB4O7 H2O) and Mg2B6O11 were determined using isothermal dissolution equilibrium method at 288.15 K. Solubilities, acidities, densities liquid phase in detail experimentally. According to experimental data, diagram relationship between density composition given. results indicate that system is a simple saturated type, double salt or solid solution are not formed There one invariant point corresponding (bischofite magnesium...
The phase equilibria of the ternary system (Li2CO3–Na2CO3–H2O) at 278.15 ≤ T/K 308.15 K were investigated by isothermal dissolution equilibrium. On basis experimental data, diagrams and densities versus mass fraction (100w) sodium carbonate plotted. For system, there is one invariant point, two univariant curves, crystallization regions corresponding to lithium (Li2CO3, LC) decahydrate (Na2CO3·10H2O, NC10) or thermonatrite (Na2CO3·H2O, NC). No solid solution double salt was found in...
Abstract Twist engineering, or the alignment of two-dimensional (2D) crystalline layers with desired orientations, has led to tremendous success in modulating charge degree freedom hetero- and homo-structures, particular, achieving novel correlated topological electronic phases moiré crystals. However, although pioneering theoretical efforts have predicted nontrivial magnetism magnons out twisting 2D magnets, experimental realization twist engineering spin remains elusive. Here, we leverage...
