Dead Burned Magnesia
- Dead Burned Magnesia
Dead burned magnesia is an important basic raw material for producing magnesia refractory bricks and bulk refractory materials. In industries such as steel, cement, glass, and other high-temperature operations, customers usually pay close attention to sintering degree, bulk density, impurity control, and long-term supply stability when selecting dead burned magnesia. These factors have a direct impact on the service life and real-world performance of refractory products.
The dead burned magnesia produced by Kuanxiang features good sintering, stable quality, and low phosphorus and sulfur content, making it well suited to the requirements of refractory production. For brick manufacturers and unshaped refractory producers, unstable raw materials often lead to frequent formula adjustments, inconsistent performance, and increased production loss. The value of a stable dead burned magnesia supply is exactly in reducing those risks.
We currently offer a full range of grades from MS-90 to MS-95, with MgO content ranging from 90% to 95% and bulk density reaching 3.18–3.20 g/cm³. Customers can select the most suitable grade according to refractory brick level, working conditions, and cost targets. For customers requiring long-term supply support, we can also provide clearer specification matching and delivery coordination.
| Item | MgO | SiO₂ | CaO | LOI | B.D. (g/cm³) |
| MS-95 | 95 | 2.2 | 1.6 | 0.3 | 3.20 |
| MS-94 | 94 | 3.0 | 1.6 | 0.3 | 3.20 |
| MS-93 | 93 | 3.5 | 1.6 | 0.3 | 3.20 |
| MS-92 | 92 | 4.0 | 1.6 | 0.3 | 3.18 |
| MS-91 | 91 | 4.5 | 1.6 | 0.3 | 3.18 |
| MS-90 | 90 | 4.8 | 2.0 | 0.3 | 3.18 |

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.
