Reactive Calcined Technical Grade Magnesium Oxide

Description

Causmag® TGM is a reactive technical grade Magnesium Oxide produced from high purity Cryptocrystalline magnesite. The distinguishing feature of TGM is its consistent high surface area, which is important to many technical applications.

Uses

Causmag® TGM is employed in an ever widening range of usage, including: Neutralizing acidic waste waters, water treatment plants, production of stock blocks, magnesium precursor of allied chemical compounds, paper production and many others.
Compared with other products commonly used as neutralizing agents, TGM is safer and easier to store and handle and has a high neutralizing capacity. Most magnesium salts formed during processing are readily soluble in water, thus ensuring a rapid, clean and efficient neutralizing operation without subsequent sludge disposal problems.
