Micro and nanostructured phases obtained by mechanical alloying - low temperature annealing in AB5-H2 systems
(Elsevier, 2015-03-02)
In this work, the characteristics of a commercial sample of LaNi5 are compared to those of an experimental one obtained by mechanical alloying followed by low temperature annealing. The nominal composition of the experimental ...
Extended and local structural description of a kaolinitic clay, its fired ceramics and intermediates: An XRD and XANES analysis
(Elsevier Science, 2016-05)
The thermal transformations processes of kaolinite (K) in kaolinitic clays is known to consist of a dehydroxylation into metakaolin (MK) at ø. 600 °C, followed by the formation of a spinel type aluminosilicate (SAS) at ø. ...
Análise microestrutural de concretos com substituição parcial de cinza de casca de arroz em altas temperaturas
(Universidade Federal de Santa MariaBrasilUFSMCentro de Tecnologia, 2021-01-21)
The usage of supplementary cementitious materials, such as rice husk ash (RHA), as a partial replacement of Portland cement is commonly studied and at room temperature may provide mechanical strength and durability to ...

Thermal, morphostructural and spectrometric characterization of an antibacterial kaolinite-based filter modified with silver for water treatment
(2020-01-01)
The aim of this work is to synthesize and characterize a new structured silver–clay dried, calcined or sintered at different temperatures composite by TG–DTA analysis, FTIR spectrometry analysis, XRD and Rietveld refinement, ...
CdMoO 4 synthesized by a microwave-assisted hydrothermal method and their photoluminescence and photocatality properties
(2012-08-20)
In this work CdMoO 4 nanoparticles were obtained under hydrothermal conditions using microwave radiation (2.45 GHz) (MH) at 100°C for different times. These powders were analyzed by X-ray diffraction (XRD), Field-emisson ...
