Application
Selected cement rotary-kiln burning and transition zones; other basic refractory positions after review.
Magnesia & spinel bricks
Magnesia–alumina spinel brick
Magnesia-alumina spinel refractory brick for selected cement-kiln lining applications. Discuss the kiln position, existing lining and required shapes.

GRADE DATA
Technical specification
Catalogue reference
Reference values for initial comparison. Confirm the selected grade and test methods for an order. Refractoriness and RUL are not continuous service-temperature ratings.
| Property | MA-S80 | MA-S85 |
|---|---|---|
| MgO (%) | 80–82 | 83–85 |
| Al₂O₃ (%) | 12–15 | 10–13 |
| RUL at 0.2 MPa (°C) | ≥1700 | ≥1700 |
| Bulk density (g/cm³) | ≥2.90 | ≥3.00 |
| Apparent porosity (%) | ≤18 | ≤16 |
| Cold crushing strength (MPa) | ≥60 | ≥80 |
| Thermal shock: 1100°C, water cooling (cycles) | ≥15 | ≥15 |
Parameters to include in your specification
- Chemical composition and impurity limits
- Bulk density, apparent porosity and cold crushing strength
- Refractoriness under load: load, endpoint and method
- Permanent linear change: temperature and holding time
- Dimensions, tolerances and joint design
