Aluminum silicate (or aluminum silicate) may be a pseudonym commonly applied to chemical compounds that are derived from aluminum oxide (Al2O3) and silica (SiO2) which can be anhydrous or hydrated, naturally occurring as minerals or synthetic. This makes out aluminum silicate(Al2SiO5) from Al2O3 & SiO2. The search for white fillers that can replace and compete with titanium dioxide has favored the amorphous aluminum silicates.
Aluminum and sodium silicate is a white-colored amorphous solid, obtained by the reaction of chemical precipitation between sodium silicate and an aluminum salt in an aqueous medium. It is a filler with many different applications, and it is used as a raw material in sectors such as the manufacture of paints, printing inks, rubber, and the paper sector.
It is also known as coal slag a dispensable abrasive which is a by-product of coal-fired electric power generation plants. This abrasive generates less dust than copper slag and is mainly used in open blasting operations in the oil- and shipyard industry

Applications of Aluminum Silicate
- Cleaning of façades and monuments (fine grains).
- Heritage restoration works (fine grains).
- High- and low-pressure blasting with portable equipment (all-grain sizes).
- Paint stripping, roughening (coarse grains).
- Outdoor blasting work (all-grain sizes).

Uses of Aluminum Silicate
Aluminum silicate (Al2SiO5) is additionally referred to as kaolin, or hydrated aluminum silicate when in powder form. Aluminum silicate is a mixture of alumina, silica, and oxygen. Kaolin is often used as a demulcent and adsorbent in the pharmaceutical industry. It is used in color lakes (insoluble dyes).
Mode of use
- Portable sand blasting machine, blast rooms, and shot blasting rooms.
- Compressed air gun blasting.
Advantages of Aluminum Silicate
- The improvement of the optical properties: a higher degree of brightness and opacity
- Cost-saving in the paint like; commercial aluminum oxide.
- An improvement of the rheological behavior of the paint thanks to its greater stability during storage, regulating the pH, maintaining a constant viscosity and acting as an anti-sedimenting agent, and
- An improvement of the properties of the paint was applied conferring greater resistance to wash and friction and less tendency to fouling.
