Molecular sieve is a synthetic hydrated aluminosilicate (zeolite) or natural zeolite with the function of screening molecules.Zeolite molecular sieve has a complex and changeable structure and a unique pore system, and is a catalyst with excellent performance. Uses of Molecular Sieves Molecular sieve is mainly caused by molecular attraction, which produces a "surface force" on the fixed surface. When the fluid flows through, some molecules in the fluid will make irregular movements and collide with the surface of the adsorbent. Molecular concentration occurs on the surface, and in the overall collision motion, the number of molecules is reduced, so as to achieve the effect of separation.

Is boron amorphous or crystalline?

Boron may be prepared as a crystalline or amorphous form. A-rhombohedral a (a-R), and b–tetragonal b (b–T) are the most well-known types of crystallization. Sometimes, it is possible to synthesize boron in the forms of a–tetragonal and g–orthotropic (g), allotropes. It is possible to also find two amorphous forms: one that is finely powdered and …
