Stability of the Aluminum Silicates

Journal of the American Ceramic Society, 1957
From the ternary phase diagrams of Al2O3–SiO2 with CaO, MgO, or FeO, it can be concluded that the free energies of formation of kyanite, andalusite, and sillimanite, according to the reaction Al2O3+ SiO2= Al2O3.SiO2, are of the order of magnitude of 0 to –10 kcal. rather than the previously accepted value of –40 to –45 kcal. However, this result may be

Aluminum silicate toxicity in cell cultures

Neuroscience, 1993
To assess the cytotoxicity of four clays containing an aluminum silicate--montmorillonite, bentonite, kaolinite and erionite--we used human umbilical vein endothelial, N1E-115 neuroblastoma, and ROC-1 oligodendroglial cells. Morphological examination, lactate dehydrogenase release and fatty acid release were used as indices of trauma.

Titanium and aluminum in siliceous sinters

Chemical Geology, 1969
Abstract The TiO 2 and Al 2 O 3 contents of siliceous sinters, formed from different thermal waters, were discussed in terms of their SiO 2 content. The sinters from acid thermal waters are characterized by their high TiO 2 Al 2 O 3 and TiO 2 SiO 2 ratios.

Fibrous aluminum silicate material

Refractories, 1980
The authors have investigated aluminosilicate fiber with organosilicon binder. They show that a rise in pressing pressure from 5 to 50 kPa, a rise in temperature from 300 to 500°C, and a rise in treatment time from 15 to 60 min enables us to obtain products with apparent densities from 0.4 to 0.65 g/cm3.

Quantitative Morphology of Aluminum Silicate Nanoaggregates

MRS Proceedings, 2002
ABSTRACTAluminum silicate nanoaggregates grown on organic multilayer templates were imaged by a transmission electron microscope. Images were processed by fractal and FOURIER analysis. The estimated mass fractal dimension suggested that aggregate formation was diffusion limited.
