Molecular Sieve type 10 Angstrom (13X) has a X type structure and is formed by arranging sold alight cases into tetrahedral stacking and bridging with the six member oxygen atom-ring . The oxygen ring provides a cavity opening of the diameter 7.4 Angstrom . But this structure adsorbs molecules upto 10 Angstroms, hence the effective diameter is specified as 10 Angstrom . Molecular Sieve can be represented by general formula -
M2 / nO [(AI2O3) . (SiO2)X]y H2O where, M represents Alkali metals with valency n.
The water of hydration which fills the cavities during crystallisation is removed by heating , with remaining cavities forming the active interior surface
We supply , Molecular Sieve in spherical form . The manufacturing process of molecular sieve is precisely controlled to exibit an efficient micropore structure and minimum attrition loss to enable the rapid diffusion of absorbate in the core of beads and for better self life .
