Type 4A

Category Description :

A main component of A-type molecular sieve is aluminosilicate, silicon-oxy and alumina tetrahedron to form a LTA-type structure, the main crystal structure is eight membered rings.

In molecular sieve 4A, sodium ion formation with a pore opening of 4Å (1Å=1×10-10m), that is type 4A (also known as NaA-type) molecular sieve.
