It's a form of aluminum silicate; cheap and easy to make from any clay, or ore, that contains aluminum.

Mullite is an aluminum silicate only described in the 20th century and is responsible for the excellent properties of the Hessian crucible.

But that would be a waste of processed aluminum silicate, which Sax did not like to see.

These minerals contain various proportions of alumina and silica, usually combined with water to form hydrous aluminum silicates.

It s composed of clay colored by iron oxide, magnesium, aluminum silicate, or potassium.

By the 1950s, precipitated aluminum silicate, called Lloyd's reagent, was being used to remove protein from serum, further improving accuracy.

Bentonite clays are primarily aluminum silicates, mixed with varying amounts of sodium, calcium, or magnesium.

The composition of that dust is limestone, sand, and aluminum silicate.

Chemicals such as sulfites, aluminum silicate, and cigarette smoke can cause EP when inhaled.

But if you look at the list of ingredients on the box you will find silica gel or aluminum silicate added (to prevent clumping).
