Manganese (Mn), is a chemical element, one of the silvery-white, hard, brittle metals of Group VII b of the periodic table. It was recognized as an element (1774) by the Swedish chemist Carl Wilhelm Scheele while working with the mineral pyrolusite and was isolated the same year by his associate, Johan Gottlieb Gahn. Although it is rarely used in pure form, manganese is essential to steelmaking. Manganese Oxide is derived from manganese, a brittle metal element. It is widely distributed in the earths crust, and is essential in steel-making. The element is needed for plant growth and in the physical development of higher animals. Manganese is involved in reducing the levels of nitrates in green plants. Lack of manganese causes testicular atrophy in animals. However, too much in either plants or animals is toxic. Manganese oxide is one of the major sources of manganese used in the dry feeds for cattle, pigs, & poultry. It helps to prevent breeding complications in cattle and ensures optimum growth for the pigs. In poultry it aids in hatchability and improves shell quality. 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. The ferrite grade manganese oxide (MnO) is not easily available in local market so sometimes manganese dioxide is reduced to manganese oxide for the ferrite grade. Ferrites are extensively used in the high-frequency magnetic cores of televisions, radios and other communications equipment such as magnetic heads, transformers and CRT deflection yokes. Ferrite may also be used as an ingredient of paints for the prevention of radio wave interference. Ferrite products currently applied in 42% of high-tech fields, such as home appliances (microwave ovens, air conditioners, and electrical home appliances), office supplies (copiers, fax machines) cars, motorcycles, high-fidelity audio, and instrument sensor parts. Middle and low areas of the application of traditional products accounted for 58%, such as speakers, adsorption magnets, toys, electrical, magnetic separation device. The growing convergence of information, communication, & entertainment is bringing a new momentum to the consumer electronics Industry in India. CE is one of the largest segments of the electronics market in India. With a market size of $5 billion in 2009 & significantly low penetration, the consumer electronics Industry in India promises huge potential in the years to come. It is estimated that the industry will grow to $11.8 billion by 2014. This growth will be aided by various factors such as increasing household incomes, local manufacturing & expanding distribution networks. The electronics industry as we know it today could not exist without the widespread use of ferrites. There is a very good scope for this product and new entrepreneurs should venture into this field.
