Magnesium Oxide Ball Granular is formed from calcined magnesite or seawater magnesia, processed into spherical granules. These granules typically range from 10 mm to 50 mm in diameter, depending on the application requirements. The ball shape ensures better flowability, uniform distribution, and easier handling compared to powder forms.
Key Characteristics:
Chemical Formula: MgO
Melting Point: ~2,852 °C
Appearance: White or light gray spherical granules
Bulk Density: 1.0 – 1.5 g/cm³ (depending on grade)
Solubility: Insoluble in water but reacts with acids
The granular form of magnesium oxide is engineered to deliver high performance in demanding environments. Below is a breakdown of its structure:
| Parameter | Specification (Typical) |
|---|---|
| MgO Content | 85% – 98% (depending on grade) |
| Fe₂O₃ Content | ≤ 0.5% |
| CaO Content | ≤ 2.0% |
| SiO₂ Content | ≤ 2.0% |
| Grain Size | 10 – 50 mm |
| Compressive Strength | > 500 kg/cm² |
The ball-shaped structure ensures reduced dust formation, improved spreading in molten steel, and uniform reactivity when used in chemical or metallurgical processes.
Acts as a slag conditioner to reduce impurities.
Provides refractory protection to furnace linings.
Reduces steelmaking costs by stabilizing slag composition.
Neutralizes acidic wastewater streams.
Adjusts pH levels efficiently due to slow, controlled dissolution.
Acts as a cost-effective alkali source.
Used in brick, crucible, and furnace lining production.
Withstands extreme temperatures and chemical corrosion.
Captures heavy metals and impurities in flue gas treatment.
Useful for desulfurization in thermal power plants.
Improves glass clarity and strength.
Acts as a stabilizer in ceramic glazes.
The method of using Magnesium Oxide Ball Granular varies by industry. Below are typical usage guidelines:
Add MgO Ball Granular directly into the furnace during refining.
Dosage: 5–15 kg per ton of steel (depending on slag condition).
Ensure uniform distribution by combining with other flux materials.
Add MgO granules to the neutralization tank.
Dosage depends on water acidity (typically 1–5 g/L).
Continuous stirring improves dissolution and neutralization.
Mix MgO Ball Granular with other refractory raw materials.
Press into molds or linings under high pressure.
Fire at temperatures above 1,500 °C to ensure bonding.
Introduce MgO granules into flue gas scrubbers.
Dosage depends on sulfur dioxide concentration.
Collect spent granules for safe disposal or recycling.
Proper storage and handling of Magnesium Oxide Ball Granular ensure consistent performance and longer shelf life.
Storage Conditions:
Store in dry, ventilated areas.
Avoid contact with moisture to prevent premature hydration.
Use palletized packaging to prevent crushing.
Handling Instructions:
Wear protective gloves and goggles.
Use dust masks when handling large volumes.
Employ mechanical loading systems for bulk handling.
Even though Magnesium Oxide Ball Granular is stable and durable, users may encounter operational issues. Below is a troubleshooting guide:
| Problem | Possible Cause | Solution |
|---|---|---|
| Granules disintegrate too quickly | High humidity during storage | Store in sealed, moisture-proof packaging |
| Poor slag conditioning in steelmaking | Incorrect dosage or low MgO purity | Check MgO content and adjust dosage |
| Slow dissolution in wastewater systems | Oversized granules | Use smaller granule size (10–20 mm) |
| Excessive dust during handling | Poor packaging or rough transport | Use reinforced packaging and gentle handling |
Shelf Life: 6–12 months under proper storage.
Inspection: Check for moisture absorption every 3 months.
Recycling: Spent granules in steelmaking can sometimes be reused in cement or construction materials.
High Thermal Stability – Ideal for high-temperature processes.
Controlled Reactivity – Granular form allows gradual dissolution.
Reduced Dust Generation – Safer and more convenient compared to powders.
Versatile Applications – Suitable across metallurgical, chemical, and environmental industries.
Cost Efficiency – Long-lasting performance with lower consumption.
Avoid direct skin and eye contact.
Use personal protective equipment (PPE) when handling.
Prevent dust inhalation by working in ventilated areas.
Dispose of spent granules according to local regulations.
| Parameter | Industrial Grade | Refractory Grade | Environmental Grade |

| Grain Size (mm) | 10–30 | 20–50 | 10–20 |
| Bulk Density | 1.2 g/cm³ | 1.4 g/cm³ | 1.0 g/cm³ |
| Application | Steelmaking | Refractory bricks | Wastewater treatment |
Q1: What is the difference between Magnesium Oxide Powder and granular ball form?
A1: The granular ball form is easier to handle, reduces dust, and provides controlled dissolution, making it more suitable for large-scale industrial use.
Q2: Can Magnesium Oxide Ball Granular replace lime in wastewater treatment?
A2: Yes, in many cases MgO provides more stable pH adjustment and less sludge formation compared to lime.
Q3: Is it safe to store MgO Ball Granular outdoors?
A3: Not recommended, as moisture can cause hydration and reduce effectiveness.
Q4: How do I select the right size of MgO granules?
A4: Choose smaller granules for faster reaction (wastewater treatment) and larger granules for longer-lasting refractory use.
