ZR3119 Zirconium dioxide fibre, ZrO2 ceramic fibre

Zirconium Dioxide Fibre (ZrO2-Ceramic Fibre) Description

The Zirconium Dioxide Fibre (ZrO2-Ceramic Fibre) exhibits high temperature resistance, strong resistance to chemical agents, and low thermal conductivity. The manufacturing process is complex. The thickened zirconium dioxide colloid is produced by the high‐technology colloid method, spun into a fibrous precursor, and subsequently converted into a polycrystalline zirconium dioxide fibre through dehydration, drying, heat treatment at medium and high temperatures, and other processes. Its chemical composition is ZrO2+Y2O3 ≥99.5%, with a classification temperature of up to 2 200℃, a melting point of up to 2 715℃, a fibre diameter of 3–6 µm, a monofilament length of 10–150 mm, and an appearance that is white, smooth, soft, and elastic.

Zirconium Dioxide Fibre (ZrO2-Ceramic Fibre) Features

1. The maximum service temperature of zirconium dioxide fibres is up to 2 200℃. Even at 2 500℃, the fibre form is maintained.
2. Good corrosion resistance is observed. The acid and alkaline corrosion resistance of ZrO2 is significantly better than that of SiO2 and Al2O3.
3. It is non-volatile and does not release contaminants at high temperatures. Among all metal oxides, ZrO2 demonstrates the lowest vapour pressure at elevated temperatures and is chemically inert.

Zirconium Dioxide Fibre (ZrO2-Ceramic Fibre) Applications

1. It is used as an ultra-high-temperature thermal protection material and as reinforcement in ceramic matrix composite materials, applied in aerospace, national defence, nuclear energy, and other key technical sectors.
2. ZrO2 fibres are employed in the production of ultra-high-temperature industrial furnaces with operating ranges from 1 500℃ to 2 200℃, ultra-high-temperature electrical test furnaces, and other high-temperature heating devices. They are used for ceramic sintering, metal melting, high-temperature decomposition, semiconductor manufacturing, quartz melting, crystal growth, experimental research, and many other areas in industrial and scientific research.
3. They serve as high-temperature filtration materials and as carriers for high-temperature reaction catalysts. Consequently, they are utilised for the high-temperature filtration of liquids or gases to remove impurities, as well as for high-temperature synthesis or cracking catalysts in chemical reactions.
