About Zeolite
Zeolite is a natural mineral formed over billions of years
What is zeolite
Zeolite
Zeolite is an emerging mineral resource in the world today. In 1756, Swedish mineralogist Kronstede brought the beautifully shaped white transparent crystals produced in the almond pores of Icelandic basalt to the laboratory. During blowing analysis and heating, there was a noticeable bubbling phenomenon, so it was named Zeolite (Greek: Zeo=Boil, Lite=stone), which means boiling stone, abbreviated as zeolite.
Zeolite is a hydrated aluminum silicate mineral of alkali or alkali earth metals. Its interior is filled with tiny pores and channels, much more complex than a honeycomb, with 1 cubic micrometer containing 1 million nanoscale pores!
Zeolite has a huge specific surface area, and the surface area of 1g modified zeolite powder is equivalent to the area of a football field.

Strong adsorption
Zeolite has a large number of pores and channels, giving it a special physical structure. Zeolite has a large specific surface area, coupled with its special crystal structure, which forms electrostatic attraction, giving it a relatively large stress field and strong adsorption performance.
Ion exchangeability
Cations such as K+, Na+, Ca2+in zeolite do not bind tightly to the crystal lattice and exhibit reversible exchange properties with other cations in aqueous solutions. Therefore, zeolite has the ability to easily exchange with surrounding cations.
Catalytic activity
The catalytic performance of zeolite is characterized by an accelerated reaction rate when a certain reactant attaches to the surface of the pores inside the zeolite crystal, and the reaction products can be diffused and released from within the zeolite, while the zeolite crystal lattice is not destroyed.
molecular sieve
The inner pores and channels of zeolite have a precise, stable and fixed diameter under physical and chemical conditions. Substances smaller than this diameter can be adsorbed by it, while substances larger than this diameter are excluded, thus having the function of molecular screening.
Acid, alkali, high temperature, and corrosion resistance
Zeolite reacts with strong acids for 2 hours at temperatures below 100 ℃, and its crystal structure remains intact; Zeolite can remain stable in aqua regia.
