What is 4A zeolite?

4A zeolite, commonly known as molecular sieve, scientific name sodium aluminosilicate, is a sodium A-type zeolite with a pore size of 0.42nm synthesized artificially. Zeolite is a beautiful crystal, because it has unique foaming characteristics when heated by blowpipe analysis. According to the meaning of "boiling stone", he named this new mineral "Zeolite" or "zeolite".

4A synthetic zeolite is a kind of crystalline silicon-aluminum compound. It is a structure composed of 8 cubic octahedrons and 12 regular tetrahedrons formed by silicon-aluminum tetrahedral units, so it is called 4A zeolite.
