What is the high temperature resistance of zirconium containing ceramic fiber blanket?

What is the high temperature resistance of zirconium containing ceramic fiber blanket? Zirconia containing ceramic fiber blanket is a high-performance high-temperature insulation material, which has significantly better high-temperature resistance than ordinary ceramic fibers (such as standard or high-purity fibers), mainly due to the addition of zirconia (ZrO ₂), effectively improving the material's structural stability and resistance to crystal phase transition at high temperatures.

Zirconia containing ceramic fiber blanket is a flexible insulation material with the first tier of high temperature resistance. The addition of zirconia achieves a balance between high temperature creep resistance and low thermal conductivity. In working conditions below 1300 ℃, its comprehensive performance (insulation efficiency, stability, and service life) is superior to most traditional refractory fibers, making it one of the preferred solutions for harsh high-temperature environments. In actual selection, a comprehensive evaluation should be conducted based on the specific temperature curve, atmosphere environment, and budget.
                                                                       

• Low thermal conductivity: about 0.22 W/(m · K) at 1000 ℃, with high insulation efficiency;
• High tensile strength: ≥ 21 MPa, not easily torn, more durable during construction and use;
• Excellent thermal stability and thermal shock resistance: it is not easy to crack or pulverize after repeated temperature rise and fall;
• Good chemical stability: suitable for neutral or weak oxidizing/reducing atmospheres, but not resistant to strong acids and bases, requiring a protective layer.
• Wide temperature resistance range: The long-term working temperature can reach around 1350 ℃, and the classification temperature can be as high as 1430 ℃, which can meet the needs of various high-temperature environments.
• Widely applicable fields: Due to its excellent high temperature resistance, zirconium containing ceramic fiber blanket is widely used in high-temperature fields such as kiln lining, boiler insulation, heat treatment temperature control, glass kiln roof insulation, furnace door sealing, flue lining, pipeline insulation, etc. At the same time, it can also be used for fire-resistant rolling shutter doors, thermal insulation components in transportation equipment, and heat sealing gaskets for household appliances.
