Role of looping-calcination conditions on self-reactivation of thermally pretreated CO2 sorbents based on CaO
(American Chemical Society, 2013)
The conversion of thermally pretreated CaO along successive carbonation/calcination cycles has been investigated, as affected by looping-calcination conditions, by means of Thermogravimetric Analysis (TGA). Sorbent samples ...

Relevance of particle size distribution to kinetic analysis: the case of thermal dehydroxylation of kaolinite
(Multidisciplinary Digital Publishing Institute (MDPI), 2021)
Kinetic models used for the kinetic analysis of solid-state reactions assume ideal conditions that are very rarely fulfilled by real processes. One of the assumptions of these ideal models is that all sample particles have ...

Electrical properties of bismuth ferrites: Bi2Fe4O9 and Bi25FeO39
(Elsevier, 2019)
Bi2Fe4O9 was prepared by solid-state reaction and the electrical properties measured by impedance spectro- scopy. After annealing in O2 at 900 °C, Bi2Fe4O9 is an electrically-homogeneous insulator. Its high frequency p ...
