A contribution to the understanding of the polyamorphism situation in triphenyl phosphite

摘要: Triphenyl phosphite (TPP) is now well known to exhibit an intriguing transformation of the supercooled liquid. The was firstly interpreted as a first-order polyamorphic transition between liquid and apparently amorphous state different from glass ordinary liquid, so-called glacial state. In this paper, we describe analyze, experimental investigations (Raman spectroscopy, calorimetric measurements, X-ray neutron diffraction), into structural organization latter heavily nucleated composed nanocrystals stable crystalline phase embedded in matrix non-transformed origin relative stability could result combination two phenomena: time lag required attain steady-state values nucleation rate (connected high viscosity TPP), temperature range where growth low. These results converge description mixed liquid/crystallites state, then contradict recent claims that TPP homogeneous phase.
