Zirconia brick (ZrO₂≥95%, 2300℃ max, bulk density ≥5.20 g/cm³) with stabilized high-purity zirconia resists ultra-high-temperature melts and atmospheres—among the highest-temperature oxide refractories.
| ZrO₂ Content | ≥95% |
|---|---|
| Max. Service Temp. | 2300℃ |
| Bulk Density | ≥5.20 g/cm³ |
| CCS | ≥60 MPa |
Zirconia bricks use stabilized zirconia: ZrO₂ ≥95%, service above 2300℃, bulk density ≥5.20 g/cm³ and CCS ≥60 MPa. Resistance to ultra-high-temperature melts and atmospheres makes them the critical choice where ordinary refractories fail—glass hot spots and ultra-high-temperature furnaces. It is Henan Songrui's cutting-edge grade for extreme service.
Costly—typically used only in critical local zones; lay in tight joints with zirconia/corundum mortar. Provide service conditions to Henan Songrui's technical team to confirm suitability.
Lay in tight joints with zirconia/corundum mortar; monitor service state in hot zones.

Cordierite-mullite kiln furniture (saggers, shelves, posts and beams) combines low thermal expansion with high refractoriness under load, offering excellent thermal shock resistance and long service life for ceramic, electronic ceramic and magnetic material kilns.
Slide gate plate is the core functional refractory of ladle and tundish slide gate systems, offering high strength, high density, excellent erosion and thermal shock resistance for precise molten steel flow control.
Ladle purge plug (corundum-spinel type) blowing argon at ladle bottom features high and stable permeability, high strength, excellent erosion and thermal shock resistance, homogenizing steel composition and removing inclusions in ladle refining.
Ladle shrouds and submerged entry nozzles are key functional refractories in continuous casting. They protect the steel stream against reoxidation and control mould flow. Alumina-carbon body with ZrO2 slag line resists slag, prevents clogging and sustains multi-heat sequences.
