Molecular sieve - Wikipedia
A molecular sieve is a material with pores (very small holes) of uniform size. These pore diameters are similar in size to small molecules, and thus large molecules cannot enter or be adsorbed, while smaller molecules can.
Molecular Sieve - an overview | ScienceDirect Topics
Molecular sieves have a pore size that is defined by the particular ion used in the preparation of the material – calcium aluminium silicate gives a pore size of 0.5 nm, whereas sodium aluminium silicate gives a pore size of approximately 1 nm. These are the two commonest molecular sieves…
Sodium aluminosilicate | AlNaO6Si2 - PubChem
Sodium aluminosilicate is a fine white powder. Many ordinary rocks (feldspars) are aluminosilicates. Aluminosilicates with more open three-dimensional structures than the feldspars are called zeolites. …

Activated Alumina | Molecular Sieve Mavens
Activated alumina is made out of aluminum oxide that is highly porous, while molecular sieve is made out crystalline metal alumino-silicates.
Molecular sieve 3A
Its lattice pore is so small 3A(1 A =10 -10 m) that it can only absorb water ; Hence, Molecular Sieve 3A have much better function of drying capacity than clay desiccant or silica gel desiccant, alumina desiccant and any others. Package: 25kg per carton packing with aluminum …
