Magnesium Oxide Heavy Extra Pure

Whatsapp Order

Magnesium Oxide Heavy Extra Pure is a high-purity, dense white powder prized for its excellent thermal stability, high melting point, and chemical inertness. It is widely used in laboratory applications as a standard reagent, pH adjuster, and desiccant. In pharmaceuticals, it functions as an antacid and a magnesium supplement, while in industrial processes, it is essential for producing refractory materials, ceramics, and insulating products due to its high heat resistance. The “heavy” form refers to its higher bulk density, making it particularly useful in applications where volume constraints are critical. Its extra pure grade ensures it meets the stringent demands of high-precision research and formulation work.
