Main Application

Magnesium Oxide is used in a number of industrial applications including:
Abrasives	As a binder in grinding wheels
Animal feed supplement	Source of magnesium ions for chickens, cattle and other animals
Boiler (oil-fired) additives	Material that is easily removed; reduced corrosion of steel pipes holding steam as well as sulfur emissions into the environment
Boiler feedwater treatment	Reduces iron, silica and solids
Chemicals	Starting point for the production of other magnesium salts such as sulfate and nitrate
Coatings	Pigment extender in paint and varnish
Construction(MgO Board)	Basic ingredient of oxychloride cements used for flooring, wallboard, fiber board, and tile
Electrical	Semi-conductors; heating elements insulating filler between wire and outer sheath
Fertilizers	Source of essential magnesium for plant nutrition
Foundries	Catalyst and water acceptor in shell molding
Glass manufacture	Ingredient for specialty, scientific and decorative glassware and fiberglass
Insulation	Light, flexible mats for insulating pipes
Lubricating oils	Additive to neutralize acids
Pharmaceuticals	Special grades of magnesium hydroxide, oxide and carbonate are used in antacids, cosmetics, toothpaste, and ointments
Plastics manufacture	Filler, acid acceptor, thickener catalyst and pigment extender
Refractory and ceramics	Basic ingredient in product formulations for the stee industry
Rubber compounding	Filler, acid acceptor, anti-scorch ingredient, curing aid, pigment
Steel industry	Annealing process; coating for grain-oriented silicon steel used in electrical transformers
Sugar refining	Reduces scale build-up when used in juice clarification and precipitation
Sulfite wood pulping	Source of base for cooking liquors
Uranium, gallium & boron	Precipitation initiator by acid neutralization processing
Wastewater treatment	Acid stream neutralizer; precipitates heavy metals

1.Magnesium Oxide For Fertilizer:

MgO is commonly used as a supplement for magnesium deficient soils especially for crops such as citrus, potatoes, vegetables, fruits and grass pastures.As we know magnesium is a required element in plant photosynthesis. Magnesium Oxide offers an available source of magnesium for various fertilizer applications.

2. Magnesium Oxide For Animal Feed and Health:

Plant forage and animal feeds are often deficient in the required magnesium levels for healthy animal nutrition. A supplemental source of magnesium is required to maintain healthy levels within a ruminant’s diet. CR MgO offers a high concentration of magnesium as well as excellent biological availability.

Magnesium deficiency in cattle and sheep can lead to a condition called grass tetany. This condition is more common in the spring and fall when levels of magnesium in the natural forage are not adequate to maintain healthy levels within the animal. Feed supplements and mineral premixes are commonly used to provide the necessary levels of magnesium to the animals to prevent grass tetany. MgO is the most widely used source of magnesium for these applications.

MgO is also an important source of magnesium for rumen buffers and dairy supplements. It offers an available source of magnesium, which aids in increasing lactational performance.

3. Magnesium Oxide For Refractory:

Magnesium oxide is used as a refractory agent in the construction of crucibles. A crucible is a container which is intended to be placed in extremely high temperatures for the sake of heating its contents. Since the crucible itself must not be affected by the heat, it must be made with substances which retain their properties at high heat. Magnesium oxide is such a substance, so it is used in this manner.

4. Magnesium Oxide For Insulator:

Due to these same heat-resistant properties, magnesium oxide powder makes an excellent insulator. It is used as the mineral component of mineral-insulated copper-clad cables, a form of industrial cable used for the protection of particularly critical electrical circuits during a fire, including fire protection devices such as alarms or smoke control systems.

5.Magnesium Oxide For Dietary Supplement:

Since it is a good source of magnesium, magnesium oxide is used as or in dietary supplements for humans and animals. In the case of animals, this is delivered as a food additive. For humans it can come in pill form or be included in multivitamins.
