The kinetics of the partial dehydration of gibbsite to activated alumina in a reactor for pneumatic transport [PDF]

open access: diamondJournal of the Serbian Chemical Society, 2001
The dehidration kinetics of gibbsite to activated alumina was investigated at four different temperatures between 883 K and 943 K in a reactor for pneumatic transport in the dilute two phase flow regime.

Changes in the Glucose Concentration Affect the Formation of Humic-like Substances in Polyphenol–Maillard Reactions Involving Gibbsite [PDF]

open access: yesMolecules
The polyphenol–Maillard reaction is considered one of the important pathways in the formation of humic-like substances (HLSs). Glucose serves as a microbial energy source that drives the humification process.

Uranyl interaction with the hydrated (001) basal face of gibbsite: A combined theoretical and spectroscopic study [PDF]

open access: bronze, 2008
International audienceThe sorption of uranyl cations and water molecules on the basal (001) face of gibbsite was studied by combining vibrational and fluorescence spectroscopies together with density functional theory ͑DFT͒ computations.

A new microenvironment for the formation of clay minerals: the example of authigenic halloysite-7Å and gibbsite in a stalactite from Agios Georgios Cave, Kilkis, north Greece

open access: diamondInternational Journal of Speleology, 2015
An unusual authigenic origin for halloysite and gibbsite is reported in a stalactite from Agios Georgios Cave, Kilkis. This speleothem includes mostly pure calcite whereas minor areas of Mg-rich calcite and scarce dolomite are present in four growth ...

Mesocrystal growth through oriented sliding and attachment of nanoplates [PDF]

open access: yesNature Communications
Oriented attachment is a critical, yet poorly understood, crystal growth pathway based on the self-assembly of nanocrystals. During oriented attachment, solvent-separated particles align and coalesce through forces that enable precise rotation and ...

Phase quantification using deep neural network processing of XRD patterns [PDF]

open access: yesIUCrJ
Mineral identification and quantification are key to the understanding and, hence, the capacity to predict material properties. The method of choice for mineral quantification is powder X-ray diffraction (XRD), generally using a Rietveld refinement ...

Study on Influencing Factors of Active Silicon Content Determination in Gibbsite

open access: yesKuangchan zonghe liyong, 2022
This paper mainly studies the factors affecting the determination of active silicon content in gibbsite. Active silicon is an important index of gibbsite. A method for the determination of active silicon in gibbsite was established by inductively coupled
