Description

Magnesium Oxide is a versatile inorganic compound essential for a wide range of industrial and commercial processes. Its high thermal stability and alkaline nature make it a critical component in refractory materials, environmental remediation, and nutritional supplements. This product is indispensable for manufacturers in the construction, agriculture, pharmaceutical, and chemical processing industries seeking a reliable and high-quality source of magnesia.

Application

• Refractory & Construction: Primary raw material for manufacturing refractory bricks, crucibles, and furnace linings due to its high melting point and thermal conductivity.
• Environmental & Waste Treatment: Used as an effective adsorbent and neutralizing agent for acidic wastewater, heavy metal removal, and flue gas desulfurization.
• Agricultural & Animal Feed: Serves as a magnesium nutrient supplement in fertilizers and as an anti-caking agent and pH buffer in animal feed.
• Pharmaceutical & Nutraceutical: Utilized as an antacid and laxative in medicinal formulations, and as a magnesium source in dietary supplements (USP/FCC grades).
• Chemical Manufacturing: Acts as a precursor in the production of other magnesium compounds, a catalyst support, and a drying agent in organic synthesis.
• Rubber & Plastics: Functions as a vulcanizing agent and acid acceptor in chloroprene rubber and as a flame retardant filler in polymer composites.

Quality Control

Our Magnesium Oxide is manufactured under a stringent quality management system to ensure batch-to-batch consistency and reliability. We offer various grades, including Industrial, Food (FCC), and Pharmaceutical (USP/EP), each meeting specific purity and impurity profile requirements. A comprehensive Certificate of Analysis (COA) detailing assay, heavy metals, loss on ignition, and other critical parameters is provided with every shipment to guarantee compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and must be kept in original packaging away from moisture to prevent caking and degradation.
