Magnesium Oxide | 1309-48-4

Description :

Magnesium Oxide Supplier and Exporter for the USA

Chemical Bull supports commercial sourcing as a Magnesium Oxide supplier, distributor, wholesaler, and exporter for the USA, serving refractory manufacturers, rubber compounders, polymer businesses, wastewater-treatment companies, and industrial procurement teams.

Magnesium Oxide, CAS No. 1309-48-4, is an inorganic compound with the formula MgO, also known as magnesia. Industrial buyers should review grade, assay, reactivity, particle size, bulk density, loss on ignition, COA, SDS, and batch consistency.

Quick Answer

Magnesium Oxide is used in industrial applications including refractory products, rubber compounding, polymer processing, wastewater neutralization, specialty cements, and glass manufacturing. Performance depends on the grade and reactivity. USA buyers should specify the application, required properties, quantity, packaging, documentation, and delivery destination when requesting bulk pricing.

What Is Magnesium Oxide?

Magnesium Oxide is a white inorganic solid containing magnesium and oxygen. Its formula is MgO, and its CAS number is 1309-48-4.

Commercial grades are produced under different processing conditions, which influence surface area, density, and chemical reactivity. These differences determine suitability for industrial applications.

Light-burned or caustic-calcined grades generally provide greater reactivity, while dead-burned and fused grades are selected for different high-temperature and material requirements. Buyers should qualify the specific grade rather than select by purity alone.

Product Information

Primary Functions: Refractory raw material, neutralizing agent, acid acceptor, and specialty formulation ingredient

What Is Magnesium Oxide Used for in Industrial Applications?

Refractory Manufacturing

Suitable Magnesium Oxide grades are used in refractory bricks, castables, and furnace-lining materials.

Dead-burned magnesia is an important raw material for selected steelmaking and kiln refractories. Manufacturers should review chemistry, density, grain size, and suitability for the intended service conditions.

Rubber Compounding and Adhesives

Reactive Magnesium Oxide is used in selected rubber and adhesive systems, including applications involving chloroprene materials.

Its function can include acid acceptance and participation in curing systems. Compounders should qualify activity, dispersion, moisture sensitivity, and finished-product performance.

Polymer and Composite Processing

Suitable Magnesium Oxide grades are used as thickeners in sheet molding and bulk molding compounds and as acid acceptors in selected polymer formulations.

Processors should match reactivity, particle size, and dosage requirements to their resin system and target processing window.

Wastewater Neutralization

Reactive Magnesium Oxide is used in selected acidic wastewater neutralization and pH-control processes.

Treatment teams should evaluate reaction rate, wastewater composition, mixing requirements, and solids management. Suitability should be verified against the actual treatment stream.

Specialty Cements and Construction Materials

Magnesium Oxide is used in selected magnesia-based cement and specialty construction formulations.

Manufacturers should qualify reactivity, setting behavior, dimensional stability, and finished-material properties against the approved formulation.

Glass Manufacturing

Suitable Magnesium Oxide grades are used as magnesium-containing raw materials in selected glass formulations.

Glass producers should review purity, relevant trace impurities, particle characteristics, and compatibility with their batch composition.

Why Manufacturers Source Magnesium Oxide

High-Temperature Applications

Qualified refractory grades support material requirements in demanding furnace and kiln environments.

Useful Chemical Reactivity

Reactive grades support selected neutralization, acid-acceptance, and formulation processes.

Application-Specific Grade Selection

Defined reactivity, particle size, density, and impurity limits help buyers select material for their production process.

Bulk and Repeat Procurement

Recurring requirements can be planned around approved specifications, batch documentation, packaging, and production schedules.

Magnesium Oxide Supplier for USA Manufacturers

USA procurement teams comparing Magnesium Oxide suppliers should review MgO assay, grade designation, reactivity test and method, particle-size distribution, bulk density, moisture, loss on ignition, and relevant calcium, silica, iron, or other impurity limits.
