Zeolite - Wikipedia
For example, the major molecular sieves, 3A, 4A and 5A, are all LTA (Linde Type A). Most commercially available natural zeolites are of the MOR, HEU or ANA-types. An example of the notation of the ring structure of zeolite and other silicate materials is …
4A Zeolite: Quality Production and Reliable Delivery - STPP Group
4A Zeolite is a hydrated silicate of aluminum and either sodium or calcium—or both. Zeolite in its natural or artificial form has an extensive application in water softening, as a detergent builder, and a cracking catalyst.
