Zirconium Ceramic Fiber Blanket is an ultra-high-performance thermal insulation product manufactured by Xintai Refractory, specially engineered for applications demanding maximum temperature resistance and thermal stability. With the addition of 15–17% zirconia (ZrO₂), this fiber blanket achieves a classification temperature of 1430°C and maintains structural integrity in continuous use up to 1350°C.
Produced using a high-purity alumina-silica-zirconia blend and a spun fiber process, the blanket delivers excellent resistance to thermal shock, slag attack, and chemical corrosion, making it ideal for the most demanding insulation environments.

Frequently Asked Questions (FAQ)
Q1: What makes zirconium ceramic fiber blanket different from standard types?
A1: It contains 15–17% zirconia (ZrO₂), which enhances its resistance to higher temperatures, thermal shock, and aggressive slags, making it suitable for extreme environments above 1300°C.
Q2: Can this product be used as a hot-face lining?
A2: Yes. It is specifically designed for direct hot-face use in furnaces, kilns, and reactors operating at elevated temperatures.
Q3: Is the blanket easy to install?
A3: Absolutely. It is lightweight, flexible, and can be easily cut and shaped to fit complex equipment contours.
Q4: Do you support OEM and custom packaging?
A4: Yes. We offer OEM branding, custom sizing, and labeling based on customer requirements.
Q5: Can I customize the thickness and dimensions?
A5: Yes. We offer a variety of thicknesses (6–50 mm) and widths (typically 610 mm), and can customize sizes upon request.
