Zirconia Insert
The zirconia insert is the bore piece inside a tundish nozzle. Buyers searching zirconia insert, zirconia tundish nozzle or inserto de zircônia need this page, not a mixed data sheet.
Dedicated Zirconia Insert Specification
Figures below are the dedicated zirconia insert specification. They are not copied from the tundish nozzle TDS.
| Property | Norm |
|---|---|
| Density | ≥ 5.3 g/cc |
| Apparent porosity | 5% |
| ZrO₂ | ≥ 95% |
| SiO₂ | ≤ 0.25% |
| MgO | ≤ 0.28% |
| Fe₂O₃ | ≤ 0.1% |
| CaO | 0.04% |

Typical value shown in the Tundish Nozzle TDS
The tundish nozzle TDS prints a different typical insert analysis. It is shown here only so the two sheets can be compared without mixing the cells.
| Property | Typical |
|---|---|
| ZrO₂ | 96% |
| MgO | 2.6% |
| SiO₂ | 0.04% |
| Al₂O₃ | 0.15% |
| Bulk density | 5.25 g/cm³ |
| Apparent porosity | 7% |
These insert figures belong to the tundish nozzle TDS. They are not the dedicated zirconia insert specification.
