Product Description

Product Description

Zirconia Fiber refers to a polycrystalline fibrous material with a purity (ZrO2+ stabilizer) ≥ 99.99%, a fully stabilized cubic crystal phase, a diameter of 3–8 μm, in the form of continuous filaments, and exhibiting a white cotton-like appearance. Zirconia fiber products are various profiled components manufactured through deep processing and calcination of zirconia fibers.  
These products feature unique process design, high purity, low density, high melting point (2700°C), high service temperature (2200°C), low thermal conductivity at room temperature (0.06 W/m·K), corrosion resistance, high-temperature stability, non-volatility, pollution-free composition, long service life, and environmental friendliness.  
As the highest-temperature-resistant ultra-high-temperature refractory insulation material among known metal oxides, it is widely used in aviation, aerospace, sapphire growth furnaces, monocrystal growth furnaces, high-temperature electric furnaces, high-process microwave electric furnaces, military applications, and other high-tech fields.

About Our Products

Zirconia fiber serves as an ultra-high-temperature insulation material and is used in crystal growth furnaces, combustion furnaces exceeding 1800°C, resistance furnaces, and other high-temperature equipment for processes such as crystal growth, ceramic firing, metal melting, petroleum cracking, and other heat treatment applications and scientific research activities. Its advantages extend beyond excellent thermal insulation properties to also facilitating rapid heating and cooling of equipment.
 
In aerospace, military, and nuclear energy sectors, zirconia fiber can be employed as an ultra-high-temperature insulation material, barrier material, ablative material, and satellite battery separator material.
 
In the aerospace and aviation industries, zirconia fiber can be used as a reinforcement material in metal matrix and ceramic matrix composites. It demonstrates unique advantages particularly in composites serving heat insulation and isolation functions.
 
Zirconia fiber can also be utilized as high-temperature filtration material and catalyst support for high-temperature reactions.
 
Application
