WebJul 31, 2015 · Fig. 4 Crystallization by a wide variety of pathways. The possible pathways by which monomers form a stable bulk crystal, and the physical mechanisms that give rise to them, can have thermodynamic ( A to C) and kinetic ( D and E) origins. Each of the pathways in Fig. 1 can be associated with the mechanisms shown here.

WebFeb 1, 2024 · Crystallization mechanism of CaO–B 2 O 3 –SiO 2 –Ta 2 O 5 glass-ceramics is studied by the critical cooling rate kinetic model for the first time. • The CBST glass-ceramics containing 1 mol % Ta 2 O 5 sintered at 875 °C for 15 min had excellent dielectric properties: ε r = 6.22 and tan δ = 1.19 × 10 −3 (1 MHz). Abstract WebThe most widely accepted approach to crystallization involves a kinetic perspective that has been modified from the theory of crystallization for small molecules. The crystallization process is divided into two sections, nucleation and growth, with the Gibbs free energy serving as the key parameter for explaining both aspects.
