Kexing - Molecular Sieve
Molecular Sieve (as known as synthetic zeolite) is a micro-porous aluminosilicate crystals. It is made of silicon-oxy tetrahedron, alumina tetrahedron to form a basic skeleton structure, in which exist metal cations (e.g. Na+, K+, Ca2+, etc.) to balance the excess negative charge in the crystal. According to the type of crystal structure, zeolite consists of: A-type (LTA), X-type (FAU), Y-type and so on.
