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 | 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 |
