ZIRCONIA INSULATION MATERIAL

   Zirconia fiber is the only high-grade lightweight refractory fiber material that can meet the long-term use in an ultra-high temperature oxidizing atmosphere above 1500°C.
   In terms of composition, zirconia fiber is a polycrystalline refractory fiber material composed of pure tetragonal/cubic phase ZrO2 nano-ceramic grains. Purity (ZRO2+ stabilizer)>99.7%, the crystal should be a fully stable cubic phase, a continuous filament with a diameter of 3-8 μm, the appearance is white cotton flocculent, due to the high melting point of ZrO2 itself (2700℃), non-oxidation and other The excellent characteristics of high temperature make ZrO2 fiber have a higher use temperature than other refractory fiber varieties (such as alumina fiber, mullite fiber, aluminum silicate fiber, etc.), and the high temperature chemical stability, corrosion resistance, oxidation resistance, heat resistance Shock-proof, non-volatile and pollution-free, it is the most advanced refractory fiber material in the world.

   Product features:
   1. The operating temperature is the highest. The melting point is up to 2700°C, the maximum operating temperature is up to 2200°C, and even the complete fiber shape can be maintained up to 2500°C.
   2. Low thermal conductivity at room temperature, 0.06Wm.k
   3. High purity and low density.
   4. Corrosion resistance is the best. ZrO2's acid and alkali corrosion resistance is significantly better than SiO2 and Al2O3.
   5. Not volatile and non-polluting at high temperature. ZrO2 has the lowest high-temperature vapor pressure among all metal oxides, is chemically inert, and is not easily volatilized or polluted at high temperatures.
