	Spray-dried granular detergent containing aluminosilicate, silicate, and pyrophosphate - Patent 4019999
		The aluminosilicates of the present invention are also of interest because of their ability to lessen the deposition of the phosphate salts on exposed machine surfaces.
		The aluminosilicates prepared in the foregoing manner are characterized by a cubic crystal structure and may additionally be distinguished from other aluminosilicates on the basis of the X-ray powder diffraction pattern.
		Although completely hydrated aluminosilicate ion exchange materials are preferred herein, it is recognized that the partially dehydrated aluminosilicates having the general formula given hereinbefore are also excellently suitable for rapidly and effectively reducing the water hardness during the laundering operation.

	Aluminosilicate - Wikipedia, the free encyclopedia
		Aluminosilicate minerals are minerals that have the basic structure and composition of AlSiO
		Hydrated aluminosilicate minerals are referred to as zeolites and are porous structures that are natural occurring materials.
		They are often used for gas or liquid adsorbtion.

		The aluminosilicate deposits seen within plaques were localized in the cores of the lesions, suggesting that this was the initiating factor.
		Aluminosilicates and the ageing brain: implications for the pathogenesis of Alzheimer's disease.
		In response to my posted aluminosilicate precipitation hypothesis, Chris Exley has noted that this suggestion is not original to me and that there is no evidence that aluminosilicates will precipitate in vivo.

	TAPPI -- leading technical association for the pulp, paper, and converting industry.
		We found that the interaction between porous sodium aluminosilicate and negatively charged suspended or colloidal matters or other anionic by-products possibly derived from peroxide bleached pulp, resulted in agglomerates that could be partially removed by flotation.
		The higher price of high brightness sodium aluminosilicate compared to a relatively less bright filler such as magnesium silicate is expected to be compensated by improved retention, brightness, and opacity.
		This study evaluated the possible use of porous sodium aluminosilicate (zeolite) as a wet end filler and as a white water clarifier in dissolved air flotation.

	Analysis of the biological and chemical reactivity of zeolite-based aluminosilicate fibers and particulates - Articles ...
		The presence of toxic fibers such as asbestos in the environment plus the continuing development of new mineral or vitreous fibers requires a better understanding of the specific physical and chemical features of fibers/particles responsible for bioactivity.
		Toward that goal, we have tested aluminosilicate zeolites to establish biological and chemical structure-function correlations.
		In this study, we focused on separating the biological response (oxidative burst) and the chemical reactivity (Fenton reaction) using aluminosilicate crystals belonging to the zeolite family.

		This potentially lifesaving material is known as aluminosilicate, a very porous combination of aluminum, silicon and oxygen.
		Conservationists use aluminosilicates to clean up chemical spills; the catastrophic oil spill of the Exxon Valdez in 1989 is a notable example.
		Eventually, Doetschman hopes to alter the inside of aluminosilicates so they’ll be very acidic or basic and thereby have the ability to “chew up” anything they soak up.

	Brown University
		For more complicated silicate melt chemistries, the reduction is still dominated by the chemical diffusion of the small, divalent network-modifier cations; consequently, the silicate chemistry as measured from the free surfsce can become quite complicated.
		The surface Fe crystals have experienced vapor-phase-effected coarsening; the {111} face truncated by traces of {100} faces are clearly evident.
		Internally, 5-20nm crystals of iron are arrayed in a "string-of-pearls" morphology; the morphology is diagnostic of having network-modifying cations in the aluminosilicate melt existing in percolative channels.

	Aluminosilicate
		This material consists of aluminosilicate particles in a glassy matrix.
		The open porosity of the material was ~38% at 1000C, which is sufficiently porous for it to be used as a heat insulation material for continuous use at this temperature.
		Kyanite is an aluminosilicate used predmoninantly for refractories and ceramic bodies.

	Calculation of the Aluminosilicate Half-Life Formation Time in the 2H Evaporator
		Combining recent calculations of heat transfer for the 2H Evaporator cleaning operations and laboratory experiments for dissolution of solid samples from the pot, the authors estimated the re-formation rate for aluminosilicates during cooling.
		This calculation estimates the rate at which aluminosilicates might form during the cooling.
		Under isothermal, unseeded and sodalite/cancrinite seeded conditions, the aluminosilicate crystallization rate depended on the desilication rate to the second power.

	Aluminosilicate melts
		Similar trends are reported for other alkali aluminosilicate melts.
		Configurational entropy and heat capacity of mixing of melts above their glass transition temperatures have been calculated with the aid of the least-squares fitted equations.
		The values of these parameters indicate that as the ionization potential of the metal cations increase, configurational heat capacity of alkali aluminosilicate melts becomes temperature-dependent.

	Bob's Rock Shop: Feldspar
		The word feldspar literally translates to: feld, meaning field, and spar, meaning "easily cleaved material".
		It refers to any of several crystalline aluminosilicate minerals found in abundance in the earth's crust.
		Minerals in the feldspar group are found in many places throughout the world, in pegmatites, even meteorites, and pass through all rock and ore-forming processes: igneous, metamorphic, hydrothermal and sedimentary, yet only rarely do they occur as gemstones.

		by using aluminosilicate or phosphosilicate glasses instead of pure silica.
		These allow for high dopant concentrations without too strong clustering effects, which could cause quenching.
