An aluminosilicate is any of a variety of silicate minerals in which a proportion of the Si4+ ions are replaced by Al3+, with the excess negative charge being balanced by extra sodium, potassium, or calcium ions.

What is zeolite?
Zeolites are microporous, aluminosilicate minerals commonly used as commercial adsorbents. Zeolites are widely used in industry for water purification, as catalysts, for the preparation of advanced materials and in nuclear reprocessing. They are used to extract nitrogen from air to increase oxygen content for both industrial and medical purposes. Their biggest use is in the production of laundry detergents. They are also used in medicine and in agriculture.
What is differences between Zeolites and silica-alumina?
Though both of these substances are made of an aluminosilicate framework, there are some key differences in regard to their morphologies, physical properties, and acidity. For instance silica-alumina is an amorphous material, and zeolites on the other hand are cyrstalline in nature. A key physical difference is that zeolites are typically microporous (i.e. very small pores) and silica-alumina are mesoporous (i.e. moderate sized pores). Lastly the Bronsted acid sites on zeolites have been found to significanly stronger than those on silica-alumina, due to the homogeneity of the zeolite.
What is the Difference between lime and cement?
Lime is calcium oxide (CaO, or hydroxide Ca(OH)2); cement is a more complex compound, generally a calcium aluminosilicate.Cement is a combination of silica-alumina minerals while lime lacks this property.It does not have any particular mineral in itMinerals present in cement actually enhances the binding power of mortar so as in case of cement we have more chances of strong binding.Lime increases its volume by 2 to 3 units so it cant be used in the process of construction as it can cause eruption.Lime absorbs carbon-dioxide and ultimately forms calcium carbonate(a protective sheath)As a result, lime mortar is considered by environmentalists to be "carbon neutral." In contrast, cement production contributes greatly to global warming, as copious amounts of carbon dioxide are released during its production.
What is an aliettite?
An aliettite is a mineral, a basic magnesium aluminosilicate.
What is the percentage composition by mass of water in hydrated aluminosilicate , Al2O32SiO2.2H2O?
6.89%
What is sodium aluminum silicate used for?
There is an industrial form of sodium aluminosilicate, known as synthetic amorphous sodium aluminosilicate, that contains water. This is a series of compounds and does not have a fixed chemical composition. It is used as an additive in powdered foods to keep lumps from forming.
What is the molecular formula of permutit?
Permutit is Sodium aluminosilicate having the formula Na2O.Al2O3.Si2O4.xH2O
What type of Touchscreen does the iPad use?
iphone screens are made of Aluminosilicate Glass
What has the author Csaba Ferenc Rappensberger written?
Csaba Ferenc Rappensberger has written: 'Novel rare-earth aluminosilicate glasses and glass-ceramics'
What is a gorrila glass?
Gorrila glass is a "Corning" manufacturing product. It is a alkali-aluminosilicate sheet of glass. Basically, it is meant to be highly thin and resistant to much surface damage. It is mostly chemical strengthened glass.
Is opal an emerald?
No, opal is an amophous hydrated silicate, while emerald is the name given to green beryl, which is a beryllium aluminosilicate. There is no relation between the two, and their only similarity is that they are both popular and highly valued gemstones.
What is an anticaking agent?
An anticaking agent is used to prevent the agglomeranion of materials as powders; for example for table salt are used potassium ferrocyanide, calcium carbonate, magnesium carbonate, sodium aluminosilicate etc.
What type of glass is used on the Apple iPhone 3gs?
two glossy panels of aluminosilicate glass - the same type of glass used in the windshields of helicopters and high-speed trains. Chemically strengthened to be 20 times stiffer and 30 times harder than plastic, the glass is ultradurable and more scratch resistant than ever.
