Kinetic expression for the isothermal crystallization of poly(3‐hydroxybutyrate)–11%poly(3‐hydroxyvalerate)
(John Wiley & Sons Inc, 2004-11)
The use of polyhydroxyalkanoates as a biodegradable semicrystalline polymer is currently increasing. The prediction of crystallinity profiles produced in part with this polymer requires the knowledge of the kinetic expression. ...
Effect of feldspar addition into bioglass 45S5 composition: Crystallization kinetics and thermal transformation
(Springer, 2016-01)
Thermal transformations of glasses with formulations derived from Bioglass 45S5 with Al2O3 (≤2.5 wt %) and K2O additions through K-feldspar were studied. Crystallization kinetics and transformations were followed-up by ...
Kinetic study of crystallization of PHB in presence of hydroxy acids
(Springer, 2009-08-01)
Poly(3-hydroxybutyrate), PHB, has been structurally modified through reaction with hydroxy acids (HA) such as tartaric acid (TA) and malic acid (MA). The crystallization kinetic of the samples was evaluated by isoconversional ...

Non-isothermal crystallization of PCL/CLAY nanocomposites
(VBRI Press, 2018-06-14)
In this work, Differential Scanning Calorimetry (DSC) was used to study the crystallization behavior of nanocomposites based on polycaprolactone (PCL) reinforced with organo-montmorillonite (C20A) and organo-bentonite ...
Nucleation kinetics of crystalline phases from a kaolinitic body used in the processing of red ceramics
(Elsevier B.V., 2011-04-01)
The crystallization kinetics of red ceramic raw material from the western part of São Paulo State, Brazil, was examined by differential thermal analysis (DTA) and X-ray diffraction (XRD). The chemical composition of the ...

Crystallization kinetics study of silver-doped germanium glasses
(2019-03-01)
A series of germanium glasses in the systems (100-x)[40GeO 2 -30Bi 2 O 3 -20PbO-10TiO 2 ] – (x) AgCl with x = 0, 1, 3 and 5 (mol%) was prepared using the melt-quenching method and then characterized taking into account ...
Kinetic Study of Seed-Assisted Crystallization of ZSM-5 Zeolite in an OSDA-Free System Using a Natural Aluminosilicate as Starting Source
(American Chemical Society, 2018-10)
We studied the crystallization of ZSM-5 zeolite by hydrothermal treatment in the absence of organic structure directing agents (OSDA) at 170, 180, and 190 °C, using Perlite as a natural source of SiO2 and Al2O3. Experimental ...
