Zeolite catalyst crystals, coloured scanning electron micrograph (SEM). Zeolites are hydrated aluminosilicate minerals and have a micro-porous structure. This zeolite, boron BETA-zeolite, is used in the petrochemical industry as a catalyst for the preparation of amines. To see the crystals growing synthetically on their metal mesh, see image A632/0053. Magnification: x6670 when printed 10 centimetres wide.
