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 WebJan 12, 2024 · The rapid crystallization ability of GST is the core of phase-change memory and neuromorphic computing technology. However, due to the complex chemical bonding mechanism of GST and the relatively random kinetic process at high temperature, there are still big challenges in the theoretical study of this phase-change process.

Polymers are composed of long molecular chains which form irregular, entangled coils in the melt. Some polymers retain such a disordered structure upon freezing and readily convert into amorphous solids. In other polymers, the chains rearrange upon freezing and form partly ordered regions with a typical size of the order 1 micrometer.
