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.

Discovery and Application of Hafnium Elements with High Melting Points

Hafnium Metal is First Extracted D. Koster and Hervez, a Swedish chemist and physicist from the Netherlands, found hafnium among zircons in Greenland and Norway. The element was named Hafnium by the Latin name of Copenhagen. Hervis and Koster, in 1925, separated titanium and zirconium using the method of crystallization containing fluorosalts. They then reduced …
