Use of steel slag for CO2 capture under realistic calcium-looping conditions
(Royal Society of Chemistry, 2016)
In this study, CaO derived from steel slag pretreated with diluted acetic acid has been tested as a dry sorbent for CO capture under realistic Ca-Looping (CaL) conditions, which necessarily implies calcination under high ...

Generalized kinetic master plots for the thermal degradation of polymers following a random scission mechanism
(American Chemical Society, 2010)
In this paper, the f(α) conversion functions for random scission mechanisms have been proposed to allow for the construction of generalized master plots suitable for these kinds of mechanisms. The master plots have been ...

A Promising approach to the kinetics of crystallization processes: The sample controlled thermal analysis
(American Ceramic Society, 2017)
Constant Rate Thermal Analysis (CRTA) method implies controlling the temperature in such a way that the reaction rate is maintained constant all over the process. This method allows determining simultaneously both the ...

Insight into the BiFeO3 flash sintering process by in-situ energy dispersive X-ray diffraction (ED-XRD)
(Elsevier, 2018)
The sintering mechanism of BiFeO3 has been investigated in-situ by energy dispersive X-ray diffraction (ED-XRD) using a high-energy white collimated X-ray beam from the Advanced Photon Source (Argonne National Laboratories). ...

Electrical properties of stoichiometric BiFeO3 prepared by mechanosynthesis with either conventional or spark plasma sintering
(Wiley, 2013)
Phase-pure powders of stoichiometric BiFeO3 have been prepared by mechanosynthesis. Ceramics sintered by either conventional heating in air or spark plasma sintering (SPS) followed by oxidative anneal in air are highly ...

Pure perovskite BiFeO3–BaTiO3 ceramics prepared by reaction flash sintering of Bi2O3–Fe2O3–BaTiO3 mixed powders
(Elsevier, 2021)
In this work, the 0.67BiFeO3-0.33BaTiO3 ferroelectric ceramic was prepared by Reaction Flash Sintering (RFS). This preparation technique combines synthesis and sintering in a single Flash experiment. The starting oxides ...

Preparation of ytterbium substituted BiFeO3 multiferroics by mechanical activation
(Elsevier, 2017)
Samples in the system Bi1−xYbxFeO3 (0.02 ≤ × ≤ 0.07) have for the first time been prepared by mechanical activation followed by sintering. XRD and DSC measurements show that the solubility limit of ytterbium in the R3c ...

Nanosilica supported CaO: A regenerable and mechanically hard CO2 sorbent at Ca-looping conditions
(Elsevier, 2014)
This work presents a CO2 sorbent that may be synthesized from low-cost and widely available materials following a simple method basically consisting of impregnation of a nanostructured silica support with a saturated ...

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 ...

Preparation of phase pure, dense fine grained ceramics by conventional and spark plasma sintering of La-substituted BiFeO3 nanoparticles
(Elsevier, 2015)
High density ceramics of the system Bi1−xLaxFeO3, 0 ≤ x ≤ 0.15, have been prepared starting from nanoparticles obtained by mechanosynthesis. The ceramics have been sintered conventionally at 850 °C and by spark plasma ...
