Magnesium Oxide
Formula : MgO
Description
It is pink/white fine powder form & hygroscopic in nature. It is a high pH controller and is also used in Agricultural Industry. Magnesium Oxide is formed by decomposing Magnesium Carbonate at high temperatures, which is known as calcining.
It is white to off white in colour, tasteless, odourless, and soluble in acid and ammonia.
RMCL's Magnesium Oxide is supplied from 70 to 99% purity.
Key Highlights
- High Refractoriness – Withstands extreme temperatures, making it ideal for furnaces and kilns.
- Excellent Alkalinity – Acts as an effective neutralizing and pH-controlling agent.
- Versatile Grades – Available in caustic calcined, dead-burnt, and fused magnesia.
- High Reactivity & Stability – Offers both reactivity in chemical processes and durability in structural applications.
