Phase equilibria in the ternary systems (MgSO4+MgB4O7+H2O) and (MgSO4+Mg2B6O11+H2O) at 273.15 K and 288.15 K: solubility and polyborate distribution

Solid–Liquid Phase Equilibria and Boron Species Distribution in the Quaternary System LiCl–LiBO2–Li2B4O7–H2O at T = 323.15 K and P = 0.1 MPa

“…There were at least six boron speciesB­(OH) 3 , B­(OH) 4 – , B 3 O 3 (OH) 4 – , B 3 O 3 (OH) 5 2– , B 4 O 5 (OH) 4 2– , and B 5 O 6 (OH) 4 2– in the borate solution . The concentrations of different boron species can be roughly calculated by reaction equilibrium constants of different boron species and pH values. − In this work, the distribution for boron species in the systems LiCl–LiBO 2 –H 2 O, LiBO 2 –Li 2 B 4 O 7 –H 2 O, and LiCl–Li 2 B 4 O 7 –LiBO 2 –H 2 O was calculated.…”
