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.

Cytotoxicity of aluminum silicates in primary neuronal cultures

Neuroscience, 1993
To study their cytotoxicity, clays containing aluminum silicates were added to cultures of primary murine spinal cord neurons and differentiated N1E-115 neuroblastoma cells. Bentonite (0.1 mg/ml) and montmorillonite (0.1 mg/ml) rapidly associated with the outer membrane of both N1E-115 and neuronal cells.

Aluminum coordination in metaaluminous and peralkaline silicate melts

Contributions to Mineralogy and Petrology, 1982
Incremental amounts of Na2O and K2O added to immiscible melts in the MgO-CaO-TiO2-Al2O3 SiO2 system cause a decrease in critical temperature, phase separation and change in the pattern of Al2O3 partitioning. Al2O3, which is concentrated in the low SiO2 immiscible melts in the alkali-free system, is increasingly partitioned into the high-SiO2 immiscible

Ellipsometric study of the siliceous films formed on aluminum surfaces by silicate treatment

Frontiers in Optics, 2003
In our previous work, the saturated thickness of siliceous films formed on aluminum surface by silicate treatment was found to be less nms. Variations and the quality of the saturated thickness of the films were investigated by means of ellipsometry for a different molecular weight of silicate ions.

High-temperature microwave bilayer absorber based on lithium aluminum silicate/lithium aluminum silicate-SiC composite

Ceramics International, 2014
Abstract The microwave absorbing properties of lithium aluminum silicate (LAS) and LAS–SiC double layer composite absorbers were investigated within the frequency range of 8.2–12.4 GHz at 300–500 °C. The composite absorbers for use as high-temperature radar wave-absorbing materials were developed by hot-pressing LAS glass–ceramic and LAS–SiC ...

DEFORMATION STUDIES OF SILICATES AND ALUMINUM SILICATES OF THE ALKALIES

Journal of the American Ceramic Society, 1923
ABSTRACTThe following investigation includes studies of the two ternary systems K2O2‐Al2O3‐SiO2 and Na2O‐Al2O2‐SiO2.In each system two areas of low fusibility were found; one including members high in alkali, low in silica, and low in alumina; the other including those high in silica, low in alkali, and low in alumina.
