High Purity Magnesia
- High-Purity Magnesia
High-purity magnesia is mainly used by refractory manufacturers with stricter requirements for purity and bulk density. For producers of high-end magnesia refractory bricks and monolithic refractories, raw material purity affects not only product quality, but also high-temperature stability, erosion resistance, and consistency in the final refractory products. For that reason, high-purity magnesia is not simply a “higher-specification product,” but a critical raw material in many premium refractory systems.
Kuanxiang high-purity magnesia is produced from selected natural high-grade magnesite ore. After beneficiation and purification, the material undergoes light burning, fine grinding, briquetting, and ultra-high-temperature shaft kiln calcination. The product is characterized by high purity and strong bulk density, making it suitable for high-standard refractory brick production and monolithic refractory applications. For customers, its value lies not only in higher laboratory figures, but also in achieving more stable results during actual manufacturing.
We currently offer grades including DBM-96, DBM-97, and DBM-97.5, with MgO content up to 97.5%. Particle size can be supplied in 0–30 mm. This product is especially suitable for refractory applications that require high purity, good density, and stable performance in demanding working conditions.
| Item | MgO% ≥ | SiO₂% ≤ | CaO% ≤ | Fe₂O₃ ≤ | LOI% ≤ | B.D. (g/cm³) ≥ | Particle Size (mm) |
| DBM-97.5 | 97.5 | 0.5 | 1.10 | 0.6 | 0.2 | 3.30 | 0-30 |
| DBM-97 | 97.0 | 0.8 | 1.20 | 0.9 | 0.3 | 3.27 | 0-30 |
| DBM-96 | 96.5 | 0.9 | 1.20 | 1.0 | 0.3 | 3.25 | 0-30 |

Technical and Logistics Support in One Service Flow
A good magnesia product can still perform poorly if the grade is wrong, the sizing is not suitable, or delivery arrives too late for production. In real projects, technical fit and supply execution are closely connected. Kuanxiang treats them that way.
Export Compliance and International Trade Support
For many overseas customers, the hardest part of sourcing magnesia is not choosing the material. It is getting the paperwork, customs coordination, and delivery process right the first time.
Green and Low-Carbon Magnesia Solutions
Low-carbon sourcing is no longer a marketing preference. For many industrial buyers, especially those serving higher-standard international markets, it has become part of procurement, compliance, and long-term competitiveness.
Customized Magnesia Raw Material Supply
When refractory manufacturers source magnesia, the real issue is rarely supply alone. What matters is whether the material fits the application, remains stable from batch to batch, and arrives on schedule. That is where Kuanxiang focuses its work.
