Selected glass-regenerator and metallurgical furnace positions.
Magnesia & spinel bricks
Fused-magnesia brick — 95 grade
A basic refractory made with fused-magnesia raw material. MgO content is only one part of selection: impurity balance, porosity, bond and operating atmosphere also matter.
At a glance
Options
95-grade straight and shaped bricks; higher-purity variants by enquiry
Selection key
Confirm process chemistry and hydration protection during storage; do not assume suitability for every molten-metal or glass-contact zone.

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 | 95 grade |
|---|---|
| MgO (%) | ≥95 |
| CaO (%) | ≤1.5 |
| SiO₂ (%) | ≤1.5 |
| RUL at 0.2 MPa (°C) | ≥1650 |
| Bulk density (g/cm³) | ≥2.95 |
| Apparent porosity (%) | ≤16 |
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
