- Magnesia or
magnesium oxide is an alkaline earth metal oxide.
Magnesium oxide produced is obtained from the calcinations of naturally
occurring minerals, magnesite, MgCO3,
Other important sources of magnesium oxide are seawater, underground
deposits of brine and deep salt beds from which magnesium hydroxide
[Mg(OH)2] is processed.
- Magnesia is used
in the steel industry as a refractory brick impregnated with tar, pitch,
graphite etc to give optimum properties for corrosion resistance in
environments of basic slags, BOF furnaces or slag lines of treatment
ladles. Magnesia bricks in combination with spinel or chrome are also
used in ferroalloy, non-ferrous, glass and cement industries. Castables
and sprayables based on magnesia are used for basic refractory linings
for steel transfer applications.
- A Molten Magnesia is
air quenched to provide a very large proportion of solid free flowing
spheres of fused magnesia, a large percentage of which are smaller than
about 35 Tyler mesh, which may be used directly in electrical resistor
units without the necessity of crushing and calcining while the larger
sized spheres may be crushed if desired and can be used with the
uncrushed spheres without being calcined.
- Fused magnesia
particulates are conventionally produced in an electric arc furnace
forming a solid ingot from the molten starting material which is
thereafter mechanically crushed and ground by various means to a final
desired particle size.
- Fused Magnesite is produced by melting caustic magnesia. Fused Magnesite finds
application as insulating material in tubular heating, elements in the
electrical industry and refractory brick linings in steel furnaces.
Fused Magnesite is mainly used as an insulating material in the
electrical heating industry. The particulate material is packed into the
space between the heating coil and the outer tube in a heating element
for air or liquids. Such elements are used in IR heaters, grill
elements, tubular hot plates, and tubular heating elements for ovens,
storage heaters, radiators, continuous-flow heaters, washing machines,
coffee machines, electric irons, and industrial liquid heating
equipment.
- Magnesium is the
eighth most abundant element and constitutes about 2 percent of the
Earth’s crust. It is the third most plentiful element dissolved in
seawater, with a concentration averaging 0.13 percent. Although
magnesium is found in over 60 minerals, only dolomite, magnesite,
brucite, carnallite, and olivine are of commercial importance. Magnesium
and magnesium compounds are produced from seawater, well and lake brines
and bitterns, as well as from the minerals noted above.
- Magnesite deposits
occur in Spain, Pakistan, and the Sudan. Deposits of less than 1 million
metric tons (Mt) were reported in Mexico, Iran, the Philippines,
Australia, Egypt, and the Republic of South Africa. Small deposits also
have been noted in Cuba, Sweden, Norway, Poland, Scotland, France,
Italy, Kenya, and Tanzania. The reported estimate of 65 Mt of magnesite
(15 Mt magnesium) reserve is based in the United States
