Magnesium Oxide
Product Description
Magnesium Oxide (MgO) is a white, odorless, non-toxic powder with high thermal and chemical stability. It is widely used across industries such as refractory, agriculture, pharmaceuticals, ceramics, and environmental treatment. Depending on its reactivity and purity, it can be categorized into light and heavy grade, as well as caustic calcined or dead-burned types.
✅ Key Advantages
✔️ Excellent heat resistance for refractory applications
✔️ High purity and stable performance in chemical processing
✔️ Custom mesh sizes and reactivity available
✔️ Suitable for both technical and food/pharma grade needs
