, 1972 Data arc presented showing the changes in physical properties which occur during the calcination of Bayer-process gibbsite at temperatures up to 1400°C. The various stages of the calcination were examined using differential thermal analysis, X-ray diffraction, low-temperature nitrogen adsorption, optical and electron microscopy, and particle-size ...

Structure and thermodynamics of platelet dispersions
, 2008 Various properties of fluids consisting of platelike particles differ from the corresponding ones of fluids consisting of spherical particles because interactions between platelets depend on their mutual orientations. One of the main issues in this topic

Fluoride removal by adsorption on thermally treated lateritic soils
Bulletin of the Chemical Society of Ethiopia, 2012 The ability of lateritic soils to remove fluoride from water has been studied. Important issues considered in the study include the relation between the mineral composition of soils and their ability to remove fluoride, the effect of thermal treatment of

Mineralogical and geochemical characteristics of two bauxitic profiles, Fria, Guinea Republic [PDF]
, 1996 Bauxite deposits of the Fria district, Guinea, have been exploited since 1960. These lateritic bauxites, located on the upper parts of plateaus, result from weathering of paleozoic schists.
