Thermal oxidation kinetics of additive free polyamide 6-6 [PDF]

, 2013
Thermal aging of an additive free PA 6-6 has been elucidated at 90, 100, 120, 140, 150 and 160 C in airventiled ovens by Fourier transform infrared spectrophotometry, viscosimetry in molten state and uniaxial tensile testing.

Carbothermic Reduction of Zinc Ferrite by Microwave Heating

High Temperature Materials and Processes, 2013
The kinetics of carbothermic reduction of ZnFe2O4 in the temperature range 823–1223 K, was investigated in a microwave reactor. The mechanism of formation of ZnO and Fe3O4/FeO by decomposition of ZnFe2O4 was explained using the equilibrium calculations ...

Preparation of in-situ compatibilized PLA/starch composites and its non-isothermal pyrolysis kinetics [PDF]

E3S Web of Conferences, 2020
A fully degradable PLA/starch composite was prepared by one-step in-situ compatibilization method. The effects of raw materials ratio and maleic anhydride （MAH） dosage were studied by thermogravimetric analyzer (TG) and scanning electron microscopy (SEM).
