Magnesium oxide is a naturally occurring mineral essential for human health. It is necessary for more than 300 enzyme reactions in the body, for normal muscle function and healthy bones. In addition, magnesium is a key element for the absorption of other nutrients. It is available in various dietary supplements, and it acts as an effective antacid to help relieve heartburn and indigestion.
American Elements produces magnesium oxide granules in several sizes and forms including rod, bar, sheet, powder, and sputtering target as well as custom compositions for commercial or research applications. The granules are free flowing white with good handleability. They are insoluble in alcohol and almost insoluble in water, but they dissolve in dilute mineral acids such as hydrochloric acid. Magnesium Oxide is not conductive to electricity. However, certain perovskite structured oxides are electronically conductive finding application in the cathode of solid oxide fuel cells and oxygen generation systems.
The present invention relates to magnesium oxide granules having an average BET specific surface area of about 7 to about 50 m 2 / g, and a bulk density of about 700 to about 1000 g / L. The granules of the present invention are of high purity and can be tabletable.
The granules can be used to make a magnesium oxide tablet, and the tableting process of the magnesium oxide tablets can be improved by using the granules of the present invention. The resulting tablets are more stable than conventional magnesium oxide tablets, and they have improved tableting strength.
