Nano-sized Zeolite Zeoal

Please contact us for other specifications.

Nakamura Choukou Co., Ltd., in collaboration with Tokyo University,

developed an innovative production process for zeolite nano-particles

by utilizing the crushing and recrystallizing technology held by

the University, and succeeded in production of low-cost nano-sized

zeolite powder.

While maintaining zeolite’s inherent functions such as adsorption, this

technology allows to minimize the particle size to 50 - 300 nm.

By minimizing the particle size to an unnoticeable level by human five

senses, this technology does not damage the basic properties and

esthetics of the target objects to which the function is added. The

technology opens the door to possibilities widely, for example, optical

application which requires light transparency, and addition to tiny fibers.

This is a representative zeolite with strong hydrophilicity and it has a composition which is the same number of coordination of Si and Al. The pore size depends on the type of ionic coordinates in the molecular skeleton, and it is called together with the pore size as "4 A zeolite" because it shows 0.3 nano for K+ion, 0.4 nano for Na+ ion and 0.5 nano for Ca2+ ion. Zeolite flourish in such as gas and liquid dehydrating mate-rial and antimicrobial by ion-supporting. By refining this Linde Type A zeolite, it has been an attention material that is expected to improve

adsorption rate and optical function.

ZSM-5 is a representative high silica synthetic zeolite, its structural cord is

MFI, the unit cell composition is Nan[Al

nSi

96-nO

192]・xH

2O .Composition can be

freely changed in the range of n<27 by control of Al concentration during

synthesis process.

The hydrophobicity of ZSM-5 will increase with decreasing Al concentration.

In particular, ZSM-5 that does not inclued Al (n=0) is called silicalite-1 and

has high hydrophobicity. The pore size is slightly larger than the benzene ring

and it is known to exhibit selectivity specific to the catalytic reaction of

aromatic hydrocarbons. ZSM-5 is widely used as a catalyst in petrochemical

products, and is also used as a hydrophobic adsorbent. Furthermore, it is

also helpful as a material for automobile exhaust gas purification catalyst.

By nano-sizing ZSM-5, we believe that it can improve several performances

as a catalyst and increase adsorption speed as an adsorbent.
