Correlation between the activation energies of structural relaxation and viscous flow for BaO–P2O5–Al2O3 glasses

Atomic Structural Origin of Fictive Temperature Revealed by AZnP3O9 (A=K, Rb) Glasses

“…The classical glass former phosphate A a B b (PO 3 ) n shows rich short‐range orders and relaxation thermodynamic information [13] . Crystalline phosphates show great structural flexibility and rich structural chemistry, [14] which is shown by the diverse connection patterns of the primary PO 4 tetrahedral building unit, including monomer, dimer, trimer, ring‐like, polymer, infinite 1D chain, 2D layer or 3D network motifs (Table S1).…”

Some phosphate crystals are newly discovered to exhibit excellent nonlinear optical properties, [14] yet, the melt is very difficult to crystallize and glasses are likely to form, which promotes us to probe the vitrification process.…”
