Journal ArticleDOI
Effect of mechanochemical activation on the thermal reactions of boehmite (γ-AlOOH) and γ-Al2O3
TL;DR: In this article, the ground material thermally transforms to corundum at 940°C via γ-Al2O3, by contrast with the unground control, which forms corundrum at 1195°C through γ and δ-Al 2O3.
Journal ArticleDOI
Solid acidity of 2: 1 type clay minerals activated by selective leaching
TL;DR: In this article, various 2.1 type clay minerals were activated by H2SO4 treatment and their solid acidities were evaluated by NH3-temperature programmed desorption (TPD).
Journal ArticleDOI
Carbothermal formation of β′-sialon from kaolinite and halloysite studied by 29Si and 27Al solid state MAS NMR
TL;DR: In this article, 27Al and 29Si magic-angle spinning (NMR) and complementary X-ray diffraction (XRD) studies of carbothermal formation of sialons from kaolinite and halloysite confirm that the reaction involves the initial formation of mullite (3Al2O3·2SiO2) and amorphous silica.
Journal ArticleDOI
Synthesis and properties of inorganic polymers (geopolymers) derived from Bayer process residue (red mud) and bauxite
TL;DR: In this article, a well-reacted geopolymers were formed from highly alkaline residue from red mud (the residue remaining after extraction of alumina from bauxite by the Bayer Process) by adjusting the composition to an optimal SiO2/Al2O3 ratio of about 3 with silica fume.
Journal ArticleDOI
Preparation of Porous Silica from Mechanically Activated Kaolinite
TL;DR: In this paper, the influence of the leaching time on the porous properties and structure of the silica was studied by XRD, XRF, FTIR and BET adsorption methods.
