Magnesium trisilicate is an inorganic chemical compound of magnesium from the group of silicates .

Occurrence

Magnesium trisilicate occurs naturally as a hydrate in the form of the mineral sea foam .

Extraction and presentation

Magnesium trisilicate can be obtained by precipitation from magnesium salt solutions (e.g. magnesium chloride or magnesium sulfate ) with alkali silicates (such as sodium silicate ). By varying the initial conditions, products (hydrates) of different compositions are obtained.

properties

Magnesium trisilicate is a hygroscopic , white, odorless and tasteless powder that is insoluble in water and ethanol . The compound decomposes on contact with acids . The compound has an almost amorphous structure made up of individual layers that are irregular and not even parallel.

use

Magnesium trisilicate is used to make meerschaum pipes . It is also used as a flow aid , dye and other things in the cosmetics industry. It is also used as an antacid .
