Technical Insights and Hewin International have released the latest report on zeolites. Using direct research and market information from top university, government, and corporate labs, Technical Insights provides a complete study of zeolite history, technology, and market applications. These reports briefly review some commercial systems and devote most of its analysis to research and development efforts where application work is advancing. It also projects the sizes of the various segments of the zeolite market through 2010 - the natural and synthetic market segments.

Quantachrome Introduces a New Method for Zeolite Characterization (Technical Note 27)
Quantachrome introduces a new method for the characterization of micro- and mesoporous materials, including catalysts, separation membranes, sensors and other zeolite-based systems. The method is based on Nonlocal Density Functional Theory (NLDFT) and is designed for pore size characterization of zeolitic materials (including MCM-41) with cylindrical pores using high-resolution low-pressure argon adsorption isotherms at 87.3 K. In contrast to the widely used classical, macroscopic theories and models, the new method is microscopic in a sense that it describes the sorption and phase behavior of Ar in a narrow pore on a molecur level. This leads to a much more accurate pore size analysis for materials consisting of narrow micropores and mesopores in a diameter range from 0.5 nm up to ca. 20 nm.

A team of University of Maine chemists has reported that exposing pesticide-contaminated water to natural light and a mineral known as a zeolite can dramatically speed up the break down of the pesticide. The finding could be useful in developing technologies for protecting drinking water supplies or improving environmental quality.

C2C is a natural zeolite producer in Canada. we initiated production in January of 1999 in British Columbia, and produce zeolites with specific applications to our patented technologies in nuclear and hazardous waste encapsulation and the manufacture of LZC (Lightweight zeolite concretes). We are developing zeolite deposits in Nova Scotia which are highly crystalline materials contained within the basaltic trap rocks in the Bay of Fundy area of Nova Scotia. The zeolites from Nova Scotia include stilbite, clinoptilolite/heulendite, as well as crystalline mixes of several other species of zeolite. We are interested in collaborative work for development application for these unique zeolites.
We can be contacted through our webpage
LuVerne E.W. Hogg, President


Several years ago we purchased a trailer load of "Upplands Mineralprodukter Clinolit" for a project that was later discontinued. The zeolite (from Zeotech ab, Sweden) is still in its original packaging. If you are interested in buying this material (at a very attractive price), please contact Al Pastore, Technical Director, N. Jonas & Co., Inc. at


The second edition of Molecular Sieves: Principles of Synthesis and Identification by Rosemarie Szostak is now available in print. For details, click here.


We have developed a unique gas-solids reactor that economically supports chemical vapor deposition onto the surface of fine powders. Gas-phase deposition of chemicals onto zeolites, or other thermo-chemical modification of zeolites appears feasible. Other applications indicated are synthesis of zeolites from agricultural waste and a novel reactor design to use zeolite catalysts for gas processing.

However, the detailed knowledge of zeolite structure, modification and applications is beyond our company's skills and interests. For that reason, we are seeking a venture partner or licensee for our reactor technology. Please contact

Subject: Zeolite Deposit

We are a South Dakota based company that holds a substantial zeolite deposit which is also located in SD. The deposit was surveyed by the USGS and was found to have at least 6 million tons of high grade (>85% clinoptilolite) and roughly 100 million tons of agricultural grade zeolite (40-70% clinoptilolite).

We have determined to sell the entire deposit and are seeking potential buyers. Additional information about the deposit is available if you are aware of anyone who might be interested in knowing more about it.

Please contact us via email if you have any questions.

Thank you,
Elizabeth Moyer-Durham
