Ceramic Fiber Textiles
Zirconia Ceramic Cloth, Tape, Rope and Packing
Code prefix ZC
Zirconia ceramic cloth, tape, rope and packing are made from ceramic fiber containing 15 to 17 percent zirconia and hafnia combined, spun and then woven or braided. The zirconia raises the classification temperature to 1430 C and the continuous working temperature to 1300 C, which puts the family above standard aluminosilicate textiles and into the range where ordinary ceramic cloth would shrink and stiffen.

01 — Product description
Product description
Zirconia-containing ceramic fiber cloth, tape, rope, and packing use ceramic fiber with a total zirconium oxide and hafnium oxide content of 15%~17% as the raw material and are manufactured through spinning and weaving processes. The product has a classification temperature of 1430°C and a continuous working temperature of 1300°C.
Product parameters
| Item | Value |
|---|---|
| Color | White |
| Classification temperature | 1430°C |
| Continuous working temperature | 1300°C |
| Fiber diameter | 3~5μm |
| Aluminum oxide (Al₂O₃) | 35~40% |
| Silicon dioxide + aluminum oxide + zirconium oxide + hafnium oxide (SiO₂+Al₂O₃+ZrO₂+HfO₂) | 99% |
| Zirconium oxide + hafnium oxide (ZrO₂+HfO₂) | 15~17% |
| Iron(III) oxide (Fe₂O₃) | 0.06% |

Note: The chemical composition content is the composition of the ceramic fiber.
Product specifications
The specifications and dimensions of zirconia-containing ceramic fiber cloth, tape, rope, and packing can be customized according to customer usage requirements.
Working condition suitability and restrictions
The product classification temperature of 1430°C is the short-term tolerance temperature. Continuous use shall not exceed 1300°C. Over-temperature operation is prohibited. The product is suitable for dry static thermal insulation, sealing, and protection conditions.
Usage precautions
- Cutting, processing, and installation of ceramic fiber material generate fiber dust. Maintain ventilation during operation, wear dust-proof protective equipment, and dispose of waste in accordance with local environmental regulations.
- The product contains a small amount of organic fiber. Initial high-temperature use may produce carbonization and smoking, which is a normal process characteristic and does not affect product performance.
- Over-continuous-working-temperature and over-working-condition use are strictly prohibited. The usage status should be regularly verified in combination with actual working conditions.
- During use, regularly inspect product condition. In case of powdering, damage, shrinkage, or failure, replace promptly.
- All technical data are for reference only. Actual performance depends on usage conditions. Users should conduct their own suitability testing and comply with relevant safety regulations and standards.
02 — Characteristics
Higher classification
A 1430 C classification and 1300 C continuous duty, against 1260 C and 1000 C for standard aluminosilicate textiles.
Four product forms
Cloth, tape, rope and packing are made on the same fiber, so a specification can move between forms without changing chemistry.
Better dimensional stability
The zirconia content reduces shrinkage at temperature, which matters on door curtains and seals that must keep their length.
Where standard cloth fails
Used at the top of the ceramic range: kiln car seals, burner surrounds, high-temperature door curtains and speciality furnace work.

05 — Where it is used
- Kiln car and door seals
- Burner and burner block surrounds
- High-temperature door curtains
- Speciality furnace seals
- Expansion joint packing above 1260 C
Service limits
- The 1430 C figure is a classification temperature, not a continuous duty rating.
- Zirconia textiles cost more than standard aluminosilicate; specify them only where the duty needs the extra range.
- Check reinforcement compatibility: wire reinforcement conducts and corrodes in wet chloride service.
