Magnesium oxide 1309-48-4 2519909100
In the world of chemical materials, some substances appear simple and unremarkable, yet they shoulder critical roles across multiple fields due to their unique chemical properties. Magnesium oxide is one such material. Its molecular formula MgO appears remarkably straightforward, while CAS number 1309-48-4 provides its precise identification. The customs code 2519909100 guides its flow in international trade. The magnesium oxide supplied by Shandong Jiurunfa exemplifies this seemingly ordinary yet multifaceted role as a fundamental chemical raw material in industrial production.
The primary raw material for magnesium oxide production is natural magnesite, processed through calcination. Different calcination temperatures yield products with vastly different reactivity. Light-burned magnesium oxide, calcined at 700 to 900 degrees Celsius, exhibits high reactivity and rapid reaction rates, making it suitable for applications requiring swift chemical responses. Dead-burned magnesium oxide is calcined at 1,400 to 1,800 degrees Celsius, resulting in a dense crystal structure and strong chemical inertness, making it suitable for refractory materials. Electro-fused magnesium oxide, melted and cooled in an electric arc furnace, features more complete crystals and higher purity, used in high-end electrical insulation materials. Shandong Jiurunfa offers magnesium oxide products ranging from light-burned to heavy-burned grades to meet diverse downstream customer requirements. Each product undergoes strict control of key indicators including magnesium oxide content, calcium oxide content, and loss on ignition.
Magnesium oxide is an essential compounding agent in neoprene rubber formulations. During vulcanization, chloroprene rubber releases hydrogen chloride. If not promptly absorbed, this acidic gas catalyzes the breakage of rubber molecular chains, causing rubber products to age, harden, or even crack. As an acid acceptor, magnesium oxide rapidly reacts with hydrogen chloride to form stable magnesium chloride, preventing acidic substances from damaging the rubber. Simultaneously, magnesium oxide participates in the vulcanization reaction alongside zinc oxide to form the vulcanization system of chloroprene rubber, influencing vulcanization speed and crosslink density. Our magnesium oxide exhibits excellent dispersion and rapid reaction speed in chloroprene rubber. Rubber products made with it demonstrate outstanding heat resistance and aging resistance, finding widespread use in wire and cable sheathing, industrial rubber rollers, and automotive rubber components.
The role of magnesium oxide in the ceramics industry is equally significant. Adding an appropriate amount of magnesium oxide to ceramic glazes adjusts the expansion coefficient of the glaze surface, reducing glaze cracking. In body formulations, magnesium oxide acts as a fluxing agent, lowering the sintering temperature of ceramics and saving energy consumption. For electronic ceramics, magnesium oxide also improves dielectric properties and increases insulation resistance. Our magnesium oxide products feature high purity with minimal impurities and strictly controlled iron content. When used in white ceramics, it prevents color distortion; in electronic ceramics, it maintains stable electrical properties.
In magnesium-based building materials, magnesium oxide serves as a key raw material for producing fireproof panels and partition boards. Mixed with magnesium chloride solution and filled with sawdust, glass fiber, and other additives, it cures into various magnesium-based building products. The primary advantage of these materials is their non-combustibility and high fire resistance rating. When exposed to fire, they do not emit toxic fumes and also provide thermal insulation properties. Our magnesium oxide exhibits optimal reactivity and moderate setting/hardening speed, resulting in magnesium-based panels with high strength and consistent quality. These panels find extensive applications in architectural decoration and as core boards for fire-rated doors.
Magnesium oxide also serves unique environmental applications. It reacts with sulfur dioxide in flue gas desulfurization to form magnesium sulfite, which can be further oxidized into magnesium sulfate for recycling. In acidic wastewater treatment, magnesium oxide acts as a neutralizing agent that precipitates more readily than lime while producing less sludge. For soil remediation, it stabilizes heavy metal ions, reducing their environmental mobility. Our magnesium oxide products feature high reactivity, superior purity, and minimal impurities, delivering stable and reliable performance in environmental applications.
