Zirconia Fiber Products Lightweight Refractory Anti-oxidation

Zirconia (ZrO2) fiber is a polycrystalline oxide refractory fiber material that can be used for a long time in ultra-high temperature oxidizing atmosphere above 1600℃. Due to the high melting point (2700℃), non-oxidation and other excellent high temperature properties of ZrO2, ZrO2 fiber has a higher operating temperature and better thermal insulation performance than existing refractory fiber varieties on the domestic market.

Product Description
Zirconium oxide fiber products are lightweight refractory energy-saving materials made of yttria-stabilized zirconium oxide fibers through several processes. There is no phase change compared to pure zirconium oxide. This type of product is processed by special technology, and the product size can still maintain stability at high temperatures. Zirconia fiber products can be processed into furnace boring plates and various special-shaped products; zirconia fiber products with different densities can be customized with different strengths and thermal conductivity coefficients. The product can be used in a high temperature environment of 2200℃. It has excellent corrosion resistance.

Basic features

• High temperature resistance (up to 2400℃, long-term use 2200℃)
• High purity (ZrO2+Y2O3) ≥ 99.8%
• Anti-oxidation, corrosion resistance (stable chemical properties, excellent acid and alkali corrosion resistance)
• No powdering, no slag (smooth appearance)
• Extremely low thermal conductivity (0.099W/m·K (1400℃)
• No volatility (no organic residue)
• Customizable shape (customized processing can be carried out according to drawing requirements)
• Customizable density (different density products can be customized according to different application fields)

Typical applications
• Zirconia combined temperature field for crystal growth
• Zirconia fiber furnace for high temperature furnace
