Historical Background


Manganese was first recognized as an element in 1774 by Carl Wilhelm Scheele while working with the mineral pyrolusite, and was isolated the same year by his associate, Johan Gottlieb Gahn. 


Manganese Oxide

Manganese oxide is the most important manganese compound. Pyrolusite is the chief source of manganese and all its compounds, when derived from ores. Pyrolusite is widely used as a chemical oxidant in organic synthesis. Manganese oxide is also used as the cathode material in electric dry cells. Synthetic manganese oxide is prepared by decomposition of manganese nitrate; by reaction of manganese sulfate, oxygen and sodium hydroxide; or by electrolysis of an aqueous solution of manganese sulfate.

What Are Usage Fields Of “FRS Magnesium Oxide”?

1) FRS Magnesium Oxide in Catalysts: Magnesium oxides (magnesia) can be used as magnesium source for manufacturing catalyst compounds. 2) FRS Magnesium Oxide in Cosmetics: Magnesium oxide is used in cosmetics for manufacturing baby powders (talcum powders). It is used in dentistry for dental cements. 3) FRS Magnesium Oxide in Steel Industry: Magnesium oxides are used in the production of magnetic steel sheets. A Slurry of Magnesium oxide is prepared and is used to coat steel and the coated sheets are submitted to high temperatures. The reaction of the magnesium with the silicone steel leads on the surface to a specific structure called “Forsterite”. This structure gives specific magnetic properties to the silicon steel. 4) FRS Magnesium Oxide in Ceramics: FRS magnesium oxide is used as a sintering agent in baked enamels. The magnesium oxide is also used in glass manufacturing and it is usually used as a source of magnesium. 5) FRS Magnesium Oxide in Food: FRS MgO is used in manufacturing diet products. It is also used in production of colorants and artificial mineral waters. 6) FRS Magnesium Oxide in Plastics, Elastomers and Rubbers: FRS Magnesium oxide is being used as a rheological agent in the SMC-BMC and as a stabilizer in the automotive PVC plastisol. 7) FRS Magnesium Oxide in Sealants and Adhesives: Magnesium oxide in this section is always used as an acid acceptor

Magnesium Carbonate” Hydrate

Magnesium Carbonate” Hydrate Magnesium Carbonate Hydrate is a water insoluble Magnesium source that can easily be converted to other Magnesium compounds, such as the oxide by heating (calcination). Carbonate compounds also give off carbon dioxide when treated with dilute acids. Magnesium Carbonate Hydrate is generally immediately available in most volumes. High purity, submicron and nano-powder forms may be considered. “Farzin Rock Stone Co.” supplies many standard grades when applicable, including Mil Spec (military grade); ACS, Reagent and Technical Grade; Food, Agricultural and Pharmaceutical Grade; Optical Grade, USP and EP/BP (European Pharmacopoeia/British Pharmacopoeia) and follows applicable ASTM testing standards. Typical and custom packaging is available. Additional technical, research and safety (MSDS) information is available as is a Reference Calculator for converting relevant units of measurement.
