3A Molecular Sieve is a synthetic zeolite. The pore size is 3 Ångstroms in diameter and has undergone an ion exchange, replacing a sodium (Na) ion with a potassium (K) ion to offer a smaller pore size.

The 3A molecular sieve is an alkali metal aluminosilicate with a pore opening of approximately 3 angstroms. Type 3A is made by ion-exchanging the sodium in the type 4A sieve with potassium. The 3A molecular sieve will exclude most molecules except water, making it very selective.

The Mikro ACM® Air Classifying Mill SF is used to grind lithium carbonate and produce the specific particle size distribution required for use in high performance Lithium Ion Batteries. Ultra-fine lithium powders used in Lithium Ion battery applications, result in …

Micronization is the process of reducing a bulk solid material's particle size to the micron or submicron level. This article discusses dry powder milling techniques and their effectiveness for micronization, specifically in the pharmaceutical industry. The article looks at how mechanical, ball, and jet mills stack up against each other.

The selective rate of specific ion transport across nanoporous material is critical to biological and nanofluidic systems. Molecular sieves for ions can be achieved by steric and electrical effects. However, the radii of Na(+) and K(+) are quite similar; they both carry a …

M.H. Abd El-Salam, in Encyclopedia of Food Sciences and Nutrition (Second Edition), 2003 Corn Wet Milling. Corn wet milling is a process that gives starch as the main product output in addition to several other products, namely, oil, protein, and fiber. This process is a water-intensive technology as 1.5 m 3 of fresh water per ton of corn is needed in modern corn wet milling.
