Description
Zeolite graphic. Computer graphic of a crystal of zeolite, a mineral used as a catalyst, for absorbing gases, drying solvents and for removing molecules of a certain size (a molecular sieve). Ions are shown as purple spheres whilst inter- ionic bonds are shown as lines. Zeolites consist of a negatively-charged framework of aluminium, silicon and oxygen which surround positively- charged ions in the cavities. The properties of zeolite arise because its framework structure creates channels through which molecules may be drawn into the crystal.
