Aluminium silicate is known as E number E559.
Aluminum Silicate is chemically denoted as Al2SiO3 & is commonly used as filler in Paints.
Aluminium silicate also exhibits anti settling properties in paint.
As Aluminium silicate is rich in Silica compound so this is also used as semi reinforcing agent in rubber.
Aluminium silicate is often used as a gemstone, and is the only garnet to always be red in color.
Aluminium silicates chemical formula is Mg3Al2(SiO4)3, although there are frequently trace amounts of other elements present.
aluminium silicate is used as a white pigment in paints, printing inks and paper, where Aluminium silicate acts as a partial substitute for titanium dioxide (extender) at the same time as Aluminium silicate increases the covering power and brightness both of the paint and of the paper.
aluminium silicate is the amorphous sodium and aluminium silicate which is used as a white filler in rubber, with a moderate reinforcing nature.
Aluminium silicates application is especially indicated in the preparation of technical rubber pieces via an extrusion or injection moulding process.
Uses

Description
Aluminum silicate is a polymorph with two other minerals; kyanite and sillimanite.
A polymorph is a mineral that shares the same chemistry but a different crystal structure with another, or other, minerals.
A unique variety of andalusite is called “chiastolite”.
Aluminium silicate contains black or brown clay and/or carbonaceous material inclusioned in the crystal.
These inclusions are arranged in regular symmetrical shapes.
Usually they are in the form of a cross or X

Description
Aluminum silicate, also known as aluminium silicate, is a mixture of aluminum, silica, and oxygen that can be either a mineral, or combined with water to form a clay.
Aluminium silicate can also combine with other elements to form various other minerals or clays.
Some of these forms are used medicinally and industrially.
They retain their strength at high temperatures — a property known as being refractory.
Some of the minerals are used as gemstones.
Mineral aluminum silicate comes in three different forms — kyanite, andalusite, or sillimanite.
They all have the chemical formula Al2SiO5, but they have different crystal structures.
All three forms are rarely found in the same rock, because each occurs under different conditions of pressure and temperature.
Only kyanite and sillimanite are used industrially.
Kyanite is unusual in that Aluminium silicates hardness varies, depending on the direction of the crystals.
Some of the crystals are similar to blue sapphires and are used as gemstones.
Kyanite is also used in the making of the frequently used industrial compound mullite.
This compound has the chemical formula 3Al2O3.2SiO2.
Aluminium silicate is used as a refractory in the ceramics industry and in the manufacture of many things, including high voltage electrical insulations, glass, and heating elements.
Sillimanite can also be used as a refractory.
Aluminium silicate is used in a variety of industries.
These include glass-making, ceramics, cement, iron foundries, and metal smelting.
Aluminum silicate can be hydrated, or have water molecules associated with Aluminium silicate.
In this case, Aluminium silicate forms a clay.
Kaolin is the term for a group of clay minerals with the chemical formula of Al2O3.2SiO2.2H20.
Aluminium silicate forms a layer of two alternating crystals — one of silicon-oxygen and one of alumina.
Kaolinite is the main constituent of kaolin.
Kaolin has been used for many years to control diarrhea and to dry poison ivy and poison oak rashes.
Aluminium silicate has also been used to treat diaper rash.
Commercially, Aluminium silicate has been important in the ceramics industry, particularly for the production of fine porcelain.
Aluminium silicate is also used to manufacture cement, bricks, and insulators, among other things.
Another aluminum silicate compound found as a mineral and as a clay is magnesium aluminum silicate, which is composed of magnesium, aluminum, silica, and oxygen.
In Aluminium silicates mineral form, Aluminium silicate is a type of garnet called pyrope.
The hydrated form of magnesium aluminum silicate is a mixture of clays.
This purified mixture is commonly used as an antacid.
Aluminium silicate is also used as a thickener in beauty products and cosmetics, and as an inactive ingredient in deodorants.
Sodium aluminum silicate is also referred to as sodium aluminosilicate and is composed of sodium, aluminum, silica, and oxygen.
Two minerals of this type are albite and jadeite.
Albite has the chemical formula of NaAlSi3O8, while that of jadeite is NaAlSi2O6.
Albite is common in Earth’s crust, and breaks down under pressure to form jadeite and quartz.
Jadeite is one of the types of minerals that make up the gemstone jade.
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.
Aluminium silicate is used as an additive in powdered foods to keep lumps from forming.
Synthetic zeolites are prepared from sodium aluminosilicate.
These are minerals that are very porous, and are used commercially as adsorbents.
They are used primarily as laundry detergents, although they have a variety of other industrial uses.
Applications
Same as for clay i.e. ceramic products, refractories, colloidal suspensions, oil-well drilling fluids, filler for rubber and plastic products, films, paper coating, decolorizing oils, temporary molds, filtration, carrier in insecticidal sprays, catalyst support.
Aluminum silicate is used to prepare aluminum-silicate polymer composite (PASiC), which is an inorganic coagulant used in water treatment.

Further, Aluminium silicate is used as filler in paper, rubber and in paints.
Aluminum Silicate Description
Aluminium silicate refers to chemical compounds which are derived from aluminium oxide, Al2O3 and silicon dioxide, SiO2.
The chemical formula of aluminum silicate is Al2SiO5, but aluminum silicate is often written as Al2O3·SiO2, because most silicates have very complex structures.
Aluminium silicate is used in the manufacture of glass, ceramics, paints, printing inks, rubber, and plastics.
Aluminum Silicate Common Constituent minerals
There are three common minerals composed of aluminum silicate, most of which are found in metamorphic rocks.
* Andalusite, belongs to the orthorhombic crystal system.
* Kyanite, belonging to the triclinic system
* Sillimanite, a variety of fine sillimanite, belongs to the orthorhombic crystal system.
The composition of these three ore is aluminum silicate, but their structure is different, so they are homogeneous and different crystals.
Aluminum Silicate Applications
1. Filler for glass, pottery, paint and paint;
2. An ideal substitute for titanium dioxide and high-quality kaolin in coatings;
3. Used to make heat-resistant, fire-proof, sound-proof and heat-insulating cotton, boards, tubes, etc.
4. Used as a filler for adhesives and sealants..
